No. I mentioned the land of high level languages before. Filtering in
any Python, Ruby, Scheme, JavaScript, Java is a piece of cake and much
more flexible than pathspec. Even with shell scripts, jq could do a
much better job than pathspec. If you filter by pathspec, good luck
trying that on extensions.

It's the same reason why I will not provide a flexible way to disable
extensions. I'm not starting a JSON API for Git. I provide an index
file in JSON format. You do what you want with it. You have a format
easy enough to import to native data structures of your favorite
language.

We may have conflicting goals. For me, first priority is the debug
tool for Git developers. 3rd-party support is a stretch. I could move
all this back to test-tool, then you can provide a 3rd-party API if
you want. Or I'll withdraw this series and go back to my original
plan.
