On the other hand, we have important 1x tasks ahead if we want to control state growth and I worry that 2 HF’s a year may be too little for that to progress effectively. Maybe @AlexeyAkhunov can chime in.

Agreed! I’d like to know of specific cases requiring >2 HFs per year.

We could keep everything else in the proposal and have HFs every quarter instead of every six months, but that just seems unrealistic for now given our prior cadence.
