True, but not quite.  You would want your "git add ." to be safe in
dirty working trees---at least some folks wanted so badly enough
that "git add ." pays attention to the ".gitignore" mechanism.

But `git commit -a` would not change, even if it won't add cruft
with well curated .gitignore files.  That will be a terrible
backward incompatible change for those who expect it only deals with
the files it knows about (including the one that is not yet tracked
but its presence is known via "git add -N").
