It's supposed to work like that everyday in the Emacs bug tracker.  If
it flatters you, so much the better :-)

Yes, that is precisely what I am suggesting.  I am happy that this point
made it across.

Though there is not any need to give up on c-toggle-auto-newline if you
don't use electric-pair-mode, or if you use some other tool like
smartparens, or perhaps even my older tool autopair.el (tho those tools
might have other drawbacks that I don't known)

Yes, Alan disagrees with this.  In his view, electric- modes are abusing
the semantics of post-self-insert-hook.  Well, at least in my view of
his views :-)

João

PS: I'm cleaning up the implementation of the more powerful
electric-layout mode in branch
scratch/fix-33794-extend-electric-layout-mode.  I'll let you know
if/when it is merged.
