As an outsider, I'm curious what directions those are. Are you referring to effects or keyword generics or something else?
Endless bikeshedding about `Pin` would be one example. I'm also not sure keyword generics are the correct way.
The discussions around 'Pin' are the opposite of bikeshedding. It's not about what color to pick for the shed, it's about reworking the feature to make it hopefully easier to reason about and use.
