But current devs know better, right?

Huh? Current devs are trying to limit the damage by getting spam to move away from UTXO bloating methods.
No they are not, they are trying to anticipate future usecases and behaviour from bad actors, which essentially boils down to negotiation with spammers (terrorists).
If you're right and filters are the only thing keeping Bitcoin from being destroyed by spammers then we are fucked anyway. As distasteful as spam is, the smooth functioning of the network and keeping the cost of running a node down is a higher priority imo. The fee market will determine what the best use of blockspace is.
The only thing that keeps Bitcoin from being destroyed are node runers, and filters are just part of the toolkit.
