You might get used to "RET reindents" and stop hitting TAB that often ;-)
For me one of the reasons why it's not gratuitous is because of things like:

       begin
         blabla
         blibli
       end

Go to just before "blibli" and type "end RET": notice that hitting TAB
just before RET won't help you, because you need to reindent the line
after the newline is inserted.

This is admittedly less serious for interactive editing than for
keyboard macros (and templates/skeletons/snippets), but I find the
behavior to be handy.

Indeed, we could do that.

Good point.

Again "just swapping" sounds simple, but I'm not sure what patch you
have in mind.  I think it's important for the user to be able to easily
say something like (electric-indent-mode -1) (and/or its buffer-local
equivalent) to recover the Emacs-23 behavior.
