   extraclean removes all generated files, and also all *~ and #* files.  If 
   removing these files is a potential problem, they could perhaps be kept by 
   bootstrap (or be kept conditionally to some variable).  But note that *~ 
   files are by default not created by Emacs, unless you've set 
   vc-make-backup-files to t in your init file.

vc-make-backup-files only applies for files under version control,
Non-version controlled files get backup files created by default.

So if you have a file, not under version control, its backup files
might get removed.  That extraclean deletes files it does not know
about (*~ and #*) seems like a mis-feature.
