Can we maybe decide on special commands in commit messages that cause
the buildbot to completely ignore the commit? Such things should not
limit us to what we can commit or not.

Perhaps a footer line (similar to Signed-off-by) at the end, such as:

buildbot: ignore


For reference, other services seem to use "[ci skip]" as a keyword that
can appear anywhere in the commit message.
