I agree with your proposal, great job.

Is there anything that we could make to make to take away common_type 
dependencies?

A single utility seems very little to split between type_traits.core and 
type_traits, but it's a bit annoying type_traits.v2 is not free of any 
other dependencies.  Embedding typeof in typetraits seems impossible as 
it needs a lot of metaprogramming and preprocessor machinery.

Best,
