It would help, but it might not be worth setting up infrastructure for
just this use case alone. Given the various platforms running tests
against the Git codebase, we probably get close to a representative
sample of the population with enough time.

I think it would be more important to have tests against HTTP/2.0. If we
did, we probably would have already caught this, e.g.
t/t5551-http-fetch-smart.sh:'GIT_TRACE_CURL redacts auth details' and
friends.

Ah, you're right. Thanks.
