Dear GHC Steering Committee

Proposal #601 says

We propose a categorization scheme for Haskell language extensions. This scheme is simple, in that there are few categories that are described in terms of the user-relevant aspects, and it is actionable, in that it suggests concrete changes to the warning system of GHC that allow users to express their own risk tolerance and get guidance as they upgrade their compiler

I'm happy with this proposal: it seems simple, comprehensible, and actionable. 

The only question in my mind is whether it is worth the bother.  I'd love to hear from the practitioners on the committee.

But I propose that we accept it.

Dear Committee,

David Thrane Christiansen suggested to categorize extensions into
Experimental, Mature, Deprecated and Legacy, and add warning flag to
GHC that allow users to be warned about (or shouted at for) using such
extensions, if they choose so.

Because of the meta-like aspect of this proposal, I’d like to assign
this to Simon PJ.


Please guide us to a conclusion as outlined in

Cheers,
Joachim
