Better Server Mod Rejection

[xJon]

Perhaps with integration to something like Pack Crash Info, be able to ship a modpack with configurable versions on client and server side, so when there's a mod mismatch it will also explain the modpack version mismatch between the client and server to avoid player confusion.

Another relevant example, player could not tell which version the server was and kept getting Server Mod rejections:

[IntegerLimit]

This does seem like a good idea.

Better Compatibility Checker seems to offer a similar feature, but is only 1.16.5+
