It's been discussed off-and-on over the years, but I don't think
anybody's actively working on it.

The trace2 facility has some json output. That's probably not helpful
for what you're doing, but it does mean we have basic json output
routines available.

One complication we faced is that a lot of Git's data is bag-of-bytes,
not utf8. And json technically requires utf8. I don't remember if we
simply fudged that and output possibly non-utf8 sequences, or if we
actually encode them.
