Right. It certainly isn't disastrous. Even b4 shazam <mid> will be able
to apply it, but generates a really odd looking commit message. I am
mostly mentioning this because this is one of the reasons people say
the current git/email workflow is "sloppy" (or even claim email is
broken). In this case it means you cannot easily review the actual
commit as is. And the commit message is important. It also means that
you have to do some surgery on a commit if you want to apply it for
someone. It just inhibits some automation.

Cheers,

Mark
