-Here, u r assuming miners not running full nodes, or even stateless nodes

Why not having dust limit improves Utreexo, I think (and tried to suggest
many times) separate storing of dust&other non spendable UTXOS (and their
hashes) so that they do not affect other UTXOS proofs ( and not brought
into main memory unless called as a TXO)
2) it's hard to quantify the magnitude of the incentives, which does matter.

I honestly don't get the long term perspective of miners Incentivised to
storing small dust UTXOS instead of having their values added to the fee.
