I mentioned this a about a month ago in the curseforge comments but figured I would mention it here too since you might have missed it. Better end has full sinytra connector support so using the 1.20.1 version on forge is not only completely possible but many do so. Problem is this doesn't seem to enable it's better end support even if you pass the fabric better end off as a forge mod using sinytra connectors configuration setting to do exactly that.

Guess I just want to know what the odds of better end support being re-added for connector users are.
