rules_proto deprecated and unmaintained - may need replacing with the current fashion

[oakad]

I have been using rules_proto in my projects following example set by rules_go, as I will imagine, most people do.

However, rules_proto are apparently unmaintained for quite some time now and are considered deprecated - module from the main protobuf repository must be used instead.

As rules_go don't only provide the useful go rules but also set example for user projects, should not they be updated to use the presently maintained protobuf module?

The migration story isn't that great without Bzlmod and rules_proto now mostly consists of aliases into Protobuf, so we probably won't migrate until we only support Bzlmod.
