I guess we could do that, but I think we'd hear even more screams.

The byte-compiler will complain if a defcustom doesn't have a :group and
there's no preceding defgroup (as was the case in the situation that

Then let's restrict the current system so it also complains if there's
no :group yet there are more than one preceding defgroup.
