 The package exports two functions from `@bgotink/kdl/v1-compat` to support documents written in KDL v1:
 
-- `parseWithoutFormatting` parses a KDL v1 document without storing any formatting information.
-  If the resulting document is passed to `format()`, a fresh KDL v2 document will be produced and any comments or formatting added by the original document's author will be lost.
-- `parseAndTransform` parses a KDL v1 document and transforms all linked formatting information to turn it into a valid KDL v2 document.
+- `parse` parses a KDL v1 document and transforms all linked formatting information to turn it into a valid KDL v2 document.
   If the resulting document is passed to `format()`, the resulting string will be the same document but in KDL v2 syntax. It will include all comments and formatting applied by the original document's author.
-
-These functions embed the 0.1.x version of this package as parser for KDL v1.
-This old parser is many times larger and a lot slower than the parser written for KDL v2.
-As such, it is advised to lazy-load the KDL v1 support only if needed.
-For example, if you want to read configuration that can be KDL v2 or v1:
-
-```js example
-import {readFile} from "node:fs/promises";
-import {parse} from "@bgotink/kdl";
-
-export async function loadConfiguration(path) {
-	const content = await readFile(path);
-
-	try {
-		return parse(content);
-	} catch (e) {
-		const {parseWithoutFormatting} = await import("@bgotink/kdl/v1-compat");
-		try {
-			return parseWithoutFormatting(content);
-		} catch (e2) {
-			throw new AggregateError(
-				[e, e2],
-				`Failed to parse configuration at ${path}`,
-			);
-		}
-	}
-}
-```
+- `parseCompat` parses a document that's either KDL v2 or KDL v1 and returns a valid KDL v2 document.
+  This is a helper function that combines the regular `parse` function with the v1-compat `parse` function into a single function that supports both formats.
