Ah, you're again pointing out the benefit of adding more chars to
electric-indent-chars.  Fine.  We've already been in violent agreement
on this time for a long time.

Indeed electric-indent-inhibit is not meant as a user-config.
And electric-indent-mode is not meant as a buffer-local config.
So what?  There is electric-indent-local-mode which is meant as
a buffer-local user-config.

So what is the problem?  Please tell precisely what feature you miss
rather than just criticize the existing ones.

I want to keep electric-indent-mode as a global mode that determines
whether certain self-inserting keys (such as RET and others) auto-indent.

Then post in that bug explaining why the behavior is undesirable or how
hard it is to disable it.
