i think so too, but i'm also unsure of whether hamurott would still be busted in a meta with neither of those two. the spikes would be harder to keep up, sure, but let's be honest: hamurott is the cheapest hazard setter in the whole game and that includes the one that should be banned before it. i think it would probably also need to go before the hazard problem could be considered totally solved
I don't see hamurott being a big issue. it hits hard but is also really frail and hates the presence of rilla sneasler teams, since rilla can either grassy glide and kill you or uturn which deals like 70% and lets something else finish you. It also gets denied by corvi which would actually become good if both of these were banned.
Other mons like zapdos and g tusk are really good checks. It can run various items but whichever item you pick opens a specific hole in hamurott thats easy to exploit. It often only sets up one, maybe two layers of spikes which would be pretty easy to manage
