If u allow me to discuss,,,
I previously suggested storing dust UTXOS in a separate Merkle tree or
strucutre in general if we are talking about the original set.
I'm a kind of person who doesn't like to throw any thing; if it's not
needed now keep it in the basement for example.
So, if dust UTXOS making a burden keep them in secondary storage, where in
such cases u can verify then delete them.
