Assuming that there were no strings attached to collecting the data, I
would agree completely.  But since your proposing that we add code to
something that we all use, it's fair to question the benefit.

There's no doubt that information is power.  That's both the source of
the appeal, and the potential to scare off users.  Incidentally, I
suspect it's those very same shadow-users we stand to scare off.  It
might be the case that we don't know whether or not they're using
compression now, but we won't necessarily know how many we've lost if
we starting sending data offsite either.
