I believe it’s extremely important to demarcate opinions and proposals from decisions. I was made aware that several people misread this topic as an official announcement of HF’s course of actions. This discussion is an RFC for a proposal on Chris’ personal blog. HF Tech Track discussed it last Tuesday, but did not come to a conclusion yet.
Speaking of demarcation, I believe there is a certain misunderstanding here:
The Haskell Foundation would like to see Haskell installers installing both cabal-install and stack everywhere
Just to be clear: this has been proposed indeed, but is under discussion and not approved yet.
