The typing module is marked as "provisional", so you probably have to live 
with the incompatibilities.

As to your other suggestions/questions, I'm not sure where the actual 
discussion is taking place -- roughly since the migration to github python-
dev and bugs.python.org are no longer very useful for outsiders to learn 
what's going on.

A random walk over the github site found

https://github.com/python/typing/issues/392

Maybe you can make sense of that? 

Personally, I'm not familiar with the evolving type system and still 
wondering whether I should neglect or reject...
