Most of the comments so far are negative, so I'll add something positive. One thing I love about the Haskell community is how they are always questioning their assumptions and genuinely seeking the best way to do things (often drawing upon or contributing to computer science research). The core concepts behind Haskell are clean and simple (essentially something between System F and System Fω), but there's a lot of baggage on the surface that obscures that underlying elegance. We should encourage people taking an introspective look into their tools and asking how they can be better, even if certain proposals are unrealistic or controversial.
I think the author is just writing down their opinions (which are worth discussing!) and not seriously trying to start a new GHC frontend. Personally, I think Haskell is approximately stuck in a local maximum, which can only be escaped by embracing dependent types (which are actually simpler than where Haskell has been heading) rather than building increasingly complex approximations of them. Once you try a dependently typed language like Agda, Lean, Coq, or Idris, it's hard to go back to the complexity of having two (or more!) separate languages for types and programs.
Regarding the proposals in the article, the most interesting to me is (2), although I'm not sure about some of the specifics. In general, I think Haskell needs a way to graduate (or retire) language extensions, rather than having them accumulate unboundedly. It's harder to talk about Haskell when everyone is using a different flavor of it.
