Thanks to all respondents - an interesting discussion. I think I'm now equipped to respond to upstream.

Why is that? Does 8-bit data break Git somehow?

A key is a small file. It doesn't bloat the repository like a tarball
would. When a key needs replacing, the new key is entirely different
whether it's ASCII-armored or not, so there's nothing to gain by
storing a diff instead of the whole file.

ASCII-armor is for sending messages over old 7-bit protocols, just like
Base64 and UUencoding. In 8-bit-clean channels ASCII-armor doesn't
accomplish anything other than making the message slightly larger. I
can't believe that Git wouldn't be 8-bit-clean.
