I've managed to run the extension source code through Xcode's safari-web-extension-converter tool, and I was able to compile and use an extension that works on Safari 14. It just works, and it's really useful!
Would you be interested in publishing it to the Apple App Store or distributing a notarized and signed version independently?
Here's some more info on the converter process: https://developer.apple.com/documentation/safariservices/safari_web_extensions/converting_a_web_extension_for_safari
