Well, it seems like we could easily skip the _modules_http suffix, and
the difference would not nearly be so large.

The problem I have with it is that, as a user, it's yet another
concept to grasp and configure. Instead of just working with USE flags
(e.g. looking at use.desc or using ufed to review, configuring USE
flags in make.conf or package.use), I now have to find/learn a bunch
of new stuff. What packages use what USE_EXPAND things (e.g. apache
has two), what are valid values for all of these.

Where with simple USE flags, there is a single mechanism that I have
to learn and can apply across the board; with USE_EXPAND stuff, I have
to learn new stuff for each new package that adopts one or more
USE_EXPAND things.

So if this cosmetic expansion is the only advantage, that seems like a
relatively limited one (e.g. it could be improved a lot just by
formatting), and the trade-off of introducing all this extra
complexity doesn't make that much sense to me.

Cheers,
