I verified the correctness of this change by tracing the code paths through both the removed code and buildMiniflareBindingOptions.
Service bindings — kCurrentWorker rewrite was redundant:
The removed code rewrote self-referencing service bindings from { name: "my-worker" } to { name: kCurrentWorker }. In Miniflare's getCustomServiceDesignator (packages/miniflare/src/plugins/core/index.ts:359), both paths resolve identically:
kCurrentWorker→getUserServiceName(refererName)→core:user:my-worker- String
"my-worker"→getUserServiceName("my-worker")→core:user:my-worker
Since refererName equals the worker's own config name at this call site, the outputs are the same.
Service bindings — behavioral improvement confirmed:
buildMiniflareBindingOptions (packages/wrangler/src/dev/miniflare/index.ts:555-575) includes both props and fetcher-type bindings. The removed override was dropping both of these. Removing the override is a strict improvement.
Durable objects — truly redundant:
The buildMiniflareBindingOptions output for durableObjects (packages/wrangler/src/dev/miniflare/index.ts:830-851) is functionally identical to the removed re-derivation, differing only cosmetically (e.g., config.containerDOClassNames?.size vs config.containers?.length as the container guard, both derived from the same source data).
No unused imports: kCurrentWorker was the only import removed, and all remaining imports (extractBindingsOfType, getDurableObjectClassNameToUseSQLiteMap, partitionDurableObjectBindings, getImageNameFromDOClassName) are still referenced elsewhere in the file.
Changeset looks good — correctly classified as patch for wrangler, and the description accurately explains the change.
Clean removal of dead code. LGTM.

/bonk this line is redundant

Agreed — the linter catches this via pnpm check which is already listed. Removed in c11533c.
The linter already enforces no unused imports via pnpm check, making the explicit reminder unnecessary.

🔴 Self-referencing service bindings broken in vitest-pool-workers due to removed kCurrentWorker mapping
The removed code mapped self-referencing service bindings (binding.service === config.name) to kCurrentWorker, a special Miniflare symbol that routes requests back to the current worker regardless of its registered name. Without this, buildMiniflareBindingOptions (packages/wrangler/src/dev/miniflare/index.ts:559-575) uses the literal service.service value (e.g., "my-worker").
In the vitest-pool-workers context, the worker's name is overridden to vitest-pool-workers-runner-<project> at packages/vitest-pool-workers/src/pool/index.ts:285, which does NOT match config.name. So a self-referencing service binding now points to a worker name that doesn't exist in the Miniflare configuration, causing the binding to fail at runtime.
How the old code handled this
The removed code at the old lines 446-462 did:
const name = binding.service === config.name ? kCurrentWorker : binding.service;This ensured that when a worker had a service binding to itself, Miniflare would route it to the current worker via the kCurrentWorker symbol (packages/miniflare/src/plugins/core/index.ts:382), regardless of what name the worker was registered under.
Prompt for agents
In packages/wrangler/src/api/integrations/platform/index.ts, after the call to buildMiniflareBindingOptions (around line 435), re-add the kCurrentWorker mapping for self-referencing service bindings. This is needed because vitest-pool-workers renames the worker (packages/vitest-pool-workers/src/pool/index.ts:285) so service bindings that reference config.name won't resolve correctly.
Specifically:
1. Re-add the import of kCurrentWorker from miniflare at line 7
2. After line 435, add code that iterates over bindingOptions.serviceBindings and replaces any entry where the name matches config.name with kCurrentWorker, similar to what was previously done:
if (bindingOptions.serviceBindings) {
for (const [key, value] of Object.entries(bindingOptions.serviceBindings)) {
if (typeof value === 'object' && value !== null && 'name' in value && value.name === config.name) {
bindingOptions.serviceBindings[key] = { ...value, name: kCurrentWorker };
}
}
}
This preserves the props field (which the old code was dropping) while still correctly handling self-references.
