Aha. Sorry for misrepresenting your point.

But there's not necessarily just one completion. If you have cl loaded,
C-h f defu <RET> => defun
but it could also be `defun*'.

I don't think so, because <RET> is also a form of completion:
C-h f buffer-face <RET> => "buffer-face-"
<RET> => "Possible completions are:"

It is not unreasonable, of course. But neither it is unreasonable the
opposite: to understand RET as, "if there's only one completion, give
me that". I think it's useful.

It's a matter of tastes, I think.

That seems reasonable, though surely there's people who will feel as
strongly about it as you feel about the current default behavior :-)
