I believe the basic question is this: What do we win by making
CONFIG_UNIX a bool?

As it is now eople have the option of building it in, building a
module or not build it at all - I don't see why that's a bad thing.
For people who want a small core kernel (for whatever reason) and then
load additional capabilities as modules, the current situation is
good. If we remove the modular option who will bennefit?
Why not just leave it as it is?
