[bitcoin-dev] Managing block size the same way we do difficulty (aka Block75)

Agreed, the clear goal of 10 minutes per block is why the difficulty
adjustment works well. Blocks averaging 75% full is the clear goal of the
described method. That's the target to attempt.
Under Block75, there will still be full blocks. There will still be
transaction fees and a fee market. The fees will be lower than they are now
Hardcoding a cap will inevitably become a roadblock (again), and we'll be
back in the same position as we are now. Permanent solutions are preferred.
