A bother _to me_.  People are different.  People use Emacs
differently.

To me, it's a bother to care about the inserted closing
delimiters and where they might currently be - they just
get in my way.

I think that if you go the route of using such
delimiter-balancing "aids" you need to do it whole-hog.
The ability to have things automatically closed for you
_necessitates_ slurping, barfing, etc.

What you see as convenience, I see as workaround hacks,
needed only because you've turned on automatically closing
delimiters.

If things are pre-closed then, yes, of course you need
commands to pull stuff inside the closings and push stuff
outside the closings.  You want to add a list element?
OK, now you have to insert it before the proper closing
paren.

I don't want Emacs to assume where/when I want to close
a list, vector, string, etc.  I'll close it where/when
I want.

With Emacs it's _trivial_ to see which closing delimiter
corresponds to which opening delimiter.  If this were
not easy to see then, sure, maybe there would be a stronger
case for automatically inserting closing delimiters.

In Emacs it's almost impossible to accidentally leave
something unclosed or to close something in the wrong
place.  Automatic closing?  YAGNI.

FWIW: DWIM too often really means _not_ "Do what I mean"
but "Do what some programmer thought would be cool to
guess I might mean."

I don't want Mr. Electric trying to second-guess where/when
I want to close something.  I don't need that kind of "help".

It's easier for me to know whether a paren is escaped or
inside a string or whatever than it is for some "smart"
code.  I know my intentions.  DWIM code can only guess
my intentions.  And when it guesses wrong I need to go
behind it an sweep up the droppings.

But as I say, everyone's different.  It's _good_, not bad,
that such electric-delimiter modes exist.  I don't argue
against them.  With Emacs, anyone can get what s?he wants.
