Drew, there's no "Y" in "I ain't gonna need it".
Now, why would some values of "Y" want it?
(1) Discoverability. Auto-acceleration would likely happen to me
frequently, so I'd learn it. (Maybe not learn to use it, but
learn to avoid it, at least.)[1] "C-u C-u C-x } } C-3 }" is not
something I would likely try on my own, nor would I find it easy
to remember if I read about it in passing. Because of:
(2) Consistency. I can't think of any other case where an infix key
controls the behavior of a command. You wouldn't need to learn
anything special to take advantage of auto-acceleration, so it's
weakly consistent with the existing Emacs UI.
(3) Usability. Some people, like you, can estimate pretty well
whether you need C-2 or C-3. Others can't, and would need to
calculate, possibly costing more time than they save. Auto-
acceleration has no such cost of computation.
(4) Economy. The advantage of user control is smaller than you
suggest, I believe. Anything bigger than C-1 will cause you to
miss the target half the time or more. Sometimes people will need
to correct for overshooting, which means either starting over with
the inverse command or using a negative count. And even if they
undershoot they need to switch to C-1.
I don't want it badly enough to write the code, but I suspect more
users will find it useful than the UI you propose. Both are valid
proposals and worth experimenting with.
Footnotes:
[1] The excluded middle of "it happens but I learn nothing" is of
course the Unrealizable Ideal, because that means it's a perfect
optimization of my current behavior.
