While I certainly agree on P2P business models as the aircraft that can now do it without having to go via the past traditional hubs it still does very much depend on cost, competition and locations.
Looking as an example, pre Covid on the PER-LHR route, to fly business you needed a second mortgage. For the route to be undertaken, or indeed even via certain euro countries first , the cost is significantly reduced (for the sake of a few hours) . You certainly wouldn't find me up the back of a QF 787 for a non stop service to LHR (it gets so cramped and narrow) nor will you find me forking out 11000 dollars or more for biz. I'll take my chances via wonderful Doha and Qatar airlines or any other stop at the moment until the prices are a bit more realistic (for my purse strings) if that ever happens.
