I'm assuming that there is something going on with Xcode here that is blocking the use of them.
I can see Xcode advertise its public extension point in the logs.
Code Block [d <private>] <PKHost:0x157b13060> Query: { NSExtensionPointName = ( "com.apple.dt.Xcode.extension.source-editor" ); }
I can see the plugins are loaded by plugin kit.

The plugins never show up in Xcode to be used.
😢
I'll file a radar soon, but was also wondering if anyone else was seeing this.
If you saw those notes and made those changes and are still encountering issues, we'd appreciate seeing your bug report.Known Issues
A new Xcode Source Editor Extension target doesn’t automatically set up embedding XcodeKit.framework in the extension. (59274389)
Workaround: Embed XcodeKit.framework in the extension manually.
Deprecations
For compatibility with new security features in macOS 11, Xcode extensions must be built using Xcode 12 and must embed XcodeKit.framework. An Xcode extension rebuilt with these tools remains compatible with older versions of Xcode and macOS. (51822755)
