I did consider working to have fewer files, but the problem seemed to be
that each module should be usable independently (install/test/document),
so you need some form of stub in each directory. Once you do that, it
seems somewhat pointless to go to the effort of passing all the
requirements as arguments or similar. It's also the case that l3kernel
has different requirements from everything else.

Over all, there is a question of time balance. We have a lot to do on
the TeX side, and also should be aiming to move 'experimental' material
to a more 'usable' state. Thus the long-term target is for
l3kernel/l3packages to contain most (all?) of the code, which means
fewer build scripts for the most important material. So when I last
looked at the build system it did not seem like a good use of my time to
spend it rejigging a system which already works and which does not
itself add code to LaTeX3.

Certainly after pdfTeX 1.30.0, which is the base requirement to run
LaTeX3 code ;-)
