Yes.  Users should be able to chose from amongst these options.  They
shouldn't be "problematic", and that was the point of my last post.

It's not a "good defense" for somebody, like me, who doesn't like it.
It's not good for Emacs for options only to work when distinct other
options are also enabled.

Not from a user's point of view.  These two modes are wholly independent
of each other (from that user's point of view), and she should be able
to enable either or both, as desired, and have them work properly.

I think it is clear there are bugs here.  Electric indentation isn't
working.

But disabling it hits the bugs in electric indentation.
