I don't think it will help unless you are the only developer on some
repo. If you have some scripts parsing the old format, people could
choose to commit using the new format anyway and your scripts will
have to adapt (it's too late to revert because it's already part of
git history).

The transition plan could be outputing both old and new formats at the
same time (optionally allowing to disable the old one) and leave it
like that for a couple releases. Then we could stop producing the old
output and hope that all the scripts in the world have caught up. Not
a great plan.

Yeah that or Reverting:, both are better than Revert:. I guess I'll
just go with Reverts: if this patch moves forward.
