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).
