As in, we may need additional prerequisites.

I think "SHA1" is short and reasonable considering that it's basically
stating, "This test depends on Git using SHA-1."  That's all we're
stating here.

I agree that the expected lifetime of the code should not impact its
design or naming in this case.  As someone who does maintenance for a
living, I'm all too aware that code lives far longer than its expected

Sure.  I can fix this up in a reroll.
