If you want to grow the standard library you have no choice but to split 
into different binaries.

That 64k symbol limit is quite the limiter here.

Having stuff like eventloops or even just curl which are heavily tied to 
platform specifics does prevent porting even the subset that doesn't 
depend on anything on the platform. In practice nobody ports phobos but 
they do copy stuff out of it.

At some point a split will occur, a well defined split is better than 
"we can't release dmd anymore as it won't link".
