Ouch. So this means that git since v2.11 is basically leaking every
non-byte pack sent by upload-pack (so all of the ref advertisement and
want/have negotiation).
Determined experimentally that the answer is: yes.
The increase in ref advertisement is roughly linear with the size of
your packed-refs, so for most people this wasn't a big deal (and even if
you have insanely large packed-refs, it's "only" 2-3x the RAM;
potentially a problem, but only if you're close to the tipping point
already).
