It's also discussed on different forum thread, Another BIP on garbage.

The proposed gain is some negligible one time reduction in utxo disk space.
The BIP would drop over 40% of the current UTXO set, all spam with dust amounts under 1000 sats. I hardly find this negligible. And it would further incentivize spammers to go elsewhere in the future, further preserving the UTXO set from bloat.
It's negligible if you compare current UTXO size (about 11.3GB[1]) with current blockchain size (above 700GB). But it's significant when we consider RAM usage (especially during IBD), especially if you don't use storage with fast random I/O to compensate low RAM capacity.
