Dear GHC Steering Committee

We have several threads about GHC's stability in progress:

• Proposal 601: GHC extension life cycle.  This introduces the notion of a "Stable" and "Experimental" extension.  It was written by David C but has stalled now that he has stepped down as ED.
  
  
• GHC Stability Goals, builds on #601 with general rules GR1-3.  This is not a change to GHC (hence not a GHC proposal) more a clarification about how the GHC Steering Committee works.
  
  
• Proposal 620: Extensions and warnings.  This proposal keeps moving in the same direction, unifying warnings and extensions.
  
  
• Proposal 617: add -experimental flag.   This builds on #601 by providing an enforcement mechanism.  It is strongly affected by #620.

It would be good to get some of this decided.  Too much is in the air at the moment!  Personally I think:

• We can agree at least the Stable/Experimental part of #601
• The Stability Goals seem fairly uncontroversial.  Shall we just make it part of the GHC Proposal process documentation
• #620 is new; your views would be welcome
• The approach to #617 may depend on the outcome of #620.
