Let's say I don't care about making it easier on corporate

If it's simply an improvement over GIT_TRACE, then I have no problem
with that. That is:
- there is no new, permanent way to turn this one like config keys
- there's no plugin support or whatever for keeping output. Keep it to
either a file or a file descriptor like we do with GIT_TRACE.

And they can use GIT_TRACE now. If GIT_TRACE does not give enough info
(e.g. too few trace points), add them. This new proposal is more about
automation. With GIT_TRACE, which is more human friendly, I could skim
over the output and remove sensitive info before I send it out for
help. Machine-friendly format (even json) tends to be a lot more
complex and harder to read/filter this way.
