I think StandaloneKindSignatures should be included. It's true that there may be implementation bugs, but the design of them is really quite straightforward, so I don't expect design bugs. And I think it's design bugs that should hinder inclusion, much more than implementation bugs (of which I know none, at the moment).

CUSKs need to go. I see no place for them in the defaults.

I want StandaloneKindSignature in the default too, but I think that they are not battle-tested enough to be included this time around.

Let's *not* have CUSKs.  We are trying to get rid of it... it'd be deeply strange to "bless" it in GHC2020.

StandaloneKindSignatures is clearly the Right Thing. I'm sure we'll want it long term.  

It's a very graceful fit with PolyKinds.


I would really like StandaloneTypeSignatures to be part of the default, and remove CUSKs. Thoughts on this? Is it too early?
