I'm very unlikely to get used to it. Specifically, in the very
annoying case where unconventional indentation gets blown away by it
(TAB won't fix that!)

I wouldn't do that, because the right indentation for "blibli" depends
on intended semantics. That is, if I started from syntactically valid
code, after inserting "end" I now have invalid code ("end without
begin"). Non-trivial edits are required to return the buffer to
"well-formed" state, and I personally prefer the now-orphaned fragment
to retain its indentation, indicating its previous semantics.
Therefore I would go to the end of "blabla", and hit RET. Why would I
care about the "no-op" reindent? Because it might not be a no-op.
("blabla" might not be conventionally indented.)

In case of such things, I'd want to do
C-x ( C-SPC ... macro keys ... C-x C-x M-x indent-region C-x )
(except in Python, where you're screwed because block structure is
determined by indentation, so situations where determining the
appropriate number of dedents requires knowing the intended semantics
are common).

"Just swapping" is entirely independent of electric-indent-mode. It
wouldn't change the Emacs-23 behavior, just have it on different keys.
