The goal is to move the functionality that is currently in the ant
script into FalconJx. After all, it's just 2 calls to a Python script
and some file manipulation.

As to the 'second pass': that will always be needed, as the Falcons
are compilers, not optimisers. It has been discussed and dismissed
that we would write our own JS optimiser; there are so many excellent
ones available all over the place. Using the Closure Compiler gives us
the added advantage of doing an actual re-compile of the JS, instead
of plain optimisation. This means that it can achieve incredibly
efficient and small code. Please look at the 'release' output from my
proof of concept.

How is replacing Closure for RequireJS removing a dependency?

The same goes for Closure. Please look at my previous email for more
on this particular topic.

Again, I like the approach you mention as an excellent addition to the
future of Flex. I don't mind (much ;-)) that you prefer one solution
over another. What I do mind is when the choice is made based on
faulty information. This email is merely intended to put to rest some
of the FUD that seems to be going around about Closure.
