Re-reading what I wrote, I really want to emphasize something so that it
isn't missed. I think the important feature here is user consent, and
that seems to be the line that projects like Mozilla use (default to
off, and require explicit consent before sending anything off-host).

We don't have to use that line. I think "do not collect even locally" is
a reasonable line, because even collecting has performance and storage
management implications. And I don't think anybody is proposing to even
collect local telemetry without the user turning it on.

The line under discussion seems to be "implement code to collect
anything at all". That's a valid line, too, but IMHO it ends up blocking
useful features (and I think we already violate it with things like
GIT_TRACE!).
