I understand your POV, but this is turned on by default in Emacs long
ago.  So the default cannot be changed just because you personally
dislike it.  Instead, I suggest that you change the default value of
mode-line format locally.  Or remove vc-refresh-state from
find-file-hook.  Or try playing with the value of vc-display-status.
Or some other change that could do what you want; look in vc-hooks.el
for ideas.

Git is not slow on MS-Windows; I posted the numbers I measured to show
that.  Git is just much faster on GNU/Linux, so people who are
accustomed to its speed on the latter complain when they need to work
on the former.  IOW, it's a "relative complaint", not an "absolute
complaint".
