that's nice in theory ... in practice, a repo with the size of KDE/
would be just plain incredibly slow to work with. in git, status and
commit operate globally. imagine the equivalent of "svn st KDE/" each
time you want to commit something. less obviously, this also has a
tremendous effect on the speed of rebasing and other more advanced
operations. just compare qtcreator and qt - just to name one "fairly
big" and one "pretty huge" git repo.
