The trouble with removing these so abruptly is that it makes for a bad
user experience.

  Warning (initialization): An error occurred while loading ‘/home/jrn/.emacs’:

  File error: Cannot open load file, No such file or directory, git

In some sense that is the distributor's fault: just because Git
upstream stops removing the git.el file doesn't mean that the
distributor needs to.  But the same thing would happen if the user
symlinked git.el into a place that emacs could find when using
upstream Git directly.  And we are putting the distributor in a bad
place.

What do you think?  Would adding such a placeholder during a
transitional period work well for you?

Thanks,
Jonathan
