I don't really remember my exact thought at the time, but it was
probably along the lines of: "master" is special not because it's
inherently special, but because revealing it doesn't compromise the
anonymity, since it's not a user-selected name.

That's not true of other names we might see in HEAD. But if we're
turning it into "ref0" or some other special name anyway, then we
haven't revealed anything.

That said, I still lean towards just being able to dump the whole
mapping by request. That solves this problem and many more.
