Does coc support workspace/diagnostics part of the LSP spec

I was just wondering if coc supports currently the diagnostics part of the spec as mentioned here - neovim/neovim#34231.

Yes https://github.com/neoclide/coc.nvim/blob/master/src/language-client/diagnostic.ts#L444

Pull for workspace diagnostics is enabled by default :h coc-config-pullDiagnostic-workspace, the server needs to declare the capability to enable the feature.

/**
 * Diagnostic options.
 *
 * @since 3.17.0
 */
export interface [DiagnosticOptions](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#diagnosticOptions) extends [WorkDoneProgressOptions](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#workDoneProgressOptions) {
	/**
	 * An optional identifier under which the diagnostics are
	 * managed by the client.
	 */
	identifier?: string;

	/**
	 * Whether the language has inter file dependencies meaning that
	 * editing code in one file can result in a different diagnostic
	 * set in another file. Inter file dependencies are common for
	 * most programming languages and typically uncommon for linters.
	 */
	interFileDependencies: boolean;

	/**
	 * The server provides support for workspace diagnostics as well.
	 */
	workspaceDiagnostics: boolean;
