I think this is a bit harsh.
And I think persistent undo is a lot problematic and only a bit useful.
And now what? You can always disable it at compile time.
Not every file is in version control.
And that’s the problem.
You don't always have a VCS System available. Sometimes there are
constraints that prevent you from using an VCS System only for yourself.
And you can't always change that.
And even if you do use a version control system, persistent undo
allows you to undo with a smaller granularity than simply
reverting revisions in version control system.
One user added a FileWritePost autocmd to commit changed files to Git
whenever he saved. Not that I’d recommend that, but that’s a
solution.

Users of Vim find different features more or less useful.
And persistent undo is on par with window tabs in terms of usefulness,
just above floating point numbers.
As I said, nobody forces you to use vim 7.3. You can always disable it
at compile time. Or even use vim7.

Nikolai:
When tab pages appeared in Vim 7.00aa, I regarded them as not really
useful, only good for people who didn't understand the power of
split-windows (and yet I wrote an enhanced 'tabline' function, which I
still use, even before the 'guitablabel' option existed). Now that I
have so many split windows that their status lines use just about half
the screen height (even with 'winminheight' set to zero: &lines == 49,
winnr('$') == 25), I've started keeping the help on its own tab.
As for floating point numbers, I constantly use Vim as a floating-point
calculator; I wouldn't say it's a useless feature. Not a /necessary/ one
-- I could do without the trig and exp/log functions, and I could even
supply additional decimals by scaling, and evaluate orders of magnitude
mentally, as I did when using a slide rule in high school and college --
but useful, yes, and at no marginal cost (especially now that Bill's
additional functions are part of Vim 7.3a, so even the risk of bit-rot
is gone).
I don't use persistent undo (yet?), any more than I use the +perl,
+python, +ruby, +tcl, +clientserver and +profile features (and probably
a lot more) yet they're all compiled into my "Huge" gvim build. Who
knows? I may use them some day. The only "feature" which I've
specifically excluded from this build (by editing feature.h) is
+tag_old_static, as I believe that the probability that I'll ever need
that one is _really_ vanishingly small.
Best regards,
Tony.
