Please describe the new feature or change.
It'd be awesome to have the option to only install this mod on the server and still allow vanilla clients to connect

Please describe why you want this feature.
I run a small vanilla server for friends, many of which play with 100% vanilla clients. I'd be great to have this functionality.

There are other datapacks and plugins which already have this functionality some of which are supported by my armoured elytra enhancement mod. There is a list of those datapacks and plugins on the curseforge page for my mod.

Thanks for the info, that's actually a great solution! I'll close this
