 # TODO: * implement git-p4 rollback <perforce change number> for debugging
 #         to roll back all p4 remote branches to a commit older or equal to
 #         the specified change.
-#       * for git-p4 submit --direct it would be nice to still create a
-#         git commit without updating HEAD before submitting to perforce.
-#         With the commit sha1 printed (or recoded in a .git/foo file?)
-#         it's possible to recover if anything goes wrong instead of potentially
-#         loosing a change entirely because it was never comitted to git and
-#         the p4 submit failed (or resulted in lots of conflicts, etc.)
 #       * Consider making --with-origin the default, assuming that the git
 #         protocol is always more efficient. (needs manual testing first :)
