This might be a niche use case, but I wanted to use this mod as a nice-to-have, like to use it in single player but still play on regular servers. However, this mod sends invalid packets to vanilla servers, and the same in reverse, so you must use a separate profile without it. I just think it would be nice if it could detect a vanilla server (or vanilla client if installed on a server) and just not do that.

This would of course be easiest when connecting a client to a vanilla server, just disable the mod's functionality unless the mod is present on the server.
When connecting a vanilla client to a modded server, I'm not sure how difficult this would be to implement, but I imagine you could just fake any bit collection blocks as barrier blocks for those clients, thus allowing them to still connect to the server, just without being able to see the bits & chisels stuff.

Hopefully this is feasible and not too difficult to implement, because I'd love to see it.

Thank you
