<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Docs: Clarify documentation for the `xmlrpc_enabled` filter to better explain that its scope only extends to methods requiring authentication.
When the `xmlrpc_enabled` filter was initially introduced in <a href="https://core.trac.wordpress.org/changeset/21509">[21509]</a>, it was effectively intended to replace the `enable_xmlrpc' UI option, which only controlled whether authenticated XML-RPC methods were enabled, such as for publishing actions. This change clarifies the expected behavior and adds information about ways to more granularly control XML-RPC method and request behavior with related hooks.
