No, I don't agree.  First because most people don't use C-j but use
RET instead, and second because typing text linearly is far from being
the only important editing pattern.

I need your help here, I'm afraid.  And I'm obviously not the only,
because it's very common for text editors to "auto-indent on RET"
(either by default, or via a config setting).

No: python-mode, haskell-mode, and coffeescript-mode can't.

I don't see what you mean by "definition" not "suboptimal".

How so?

No, I know those wheels very well, because I suffered through many of
them.  The problem is they're not modular: your rebinding of ?{ to make
it auto-indent means that my global binding of ?{ to make it auto-pair
doesn't work in c-mode.
