The threshold for dust will be going up as the fees inevitably go up
No. Dust is not a function of tx fees. It’s a relay policy
To consolidate dust would increase the spendable circulation
What? No UTXO can increase circulation
…miners are not incentivized to do this… separate mining block only for dust consolidation
So miners are not incentivized to act against their own interest, but maybe they will?
Even with empty blocks, no one was consolidating dust. And how do you expect miner to include txs they don’t have the keys/scripts to spend. If you want to get rid of dust in your wallet, you’re better off donating it to the miners as a OP_RETURN.
