That's another problem with custom in that it handles buffer-local
settings pretty poorly.  But note that for this particular case,
it's not as bad as you make it to be since there's custom-local-buffer
to take care of it.  Admittedly many setter functions don't pay attention
to it, but that's just another thing that needs to be fixed.

No, custom-local-buffer is all you need for this particular case.
