To be clear (and I'll respond more on this later) the current version
of my Windows build is aimed toward what I guess you could call
"casual" users and is designed more toward making Sage look like a
real "software product" that one can install and have 'just work'.
There are no optional packages yet just because I haven't tested them
all on Cygwin yet, and if there ever are they'll probably be installed
from binaries, not compiled on the user's local machine.

It's not intended for developers of Sage or "power users" who want to
compile and fine-tune their own packages.
