So I'll take back the claims of any big regression. I was just able to
build the tips of the various modules and still get ~ 95k glyphs/sec.,
(that's still not *fast* but it's also not a _huge_ regression
compared to ~ 100k glyphs/sec. I had before updating).

So, there must have been other things going on in the various side
branches that were causing the ~ 30k glyphs/sec. results I was
seeing. I had assumed there was some mainline regression since I saw
the 30k number in both some experimental EXA branches as well as when
running EXA on the glucose branches.

I don't have the motivation of chasing down this particular regression
anymore. But I will still try out some git supermodule things for the
benefit of cross-module tagging etc.

I'll post that here when I do it.
