True! But in this case, the issue for most part wasn't just a delay because work took longer - but the question of whether or not it can be mathematically proven to work was open (and if it can't be proven to be possible and working, there's no point in trying). My intuition told me the result will be "it's not possible; waste in PoW is fundamental to these kinds of structures". I'm relieved to see I was wrong.
