Isn't a libraries-only global frameworks install what we released for beta1? 
Sure, the plan for beta2 is a general SDK.

Frameworks are not getting renamed. That would break source compatibility too.

Sure, that's runtime though.

A-ha! That's exactly the point, then. If Mac developers do not expect global 
frameworks for development, then we shouldn't provide it, we shouldn't bother 
to support it and we don't have to worry about making them work.

Agreed.

So on both Mac and Windows, Qt libraries are always installed on their own 
prefixes. There's no global install. That means there's no conflict of names 
either, in either libraries or tooling.
