I don't think deanonymizing dust attacks are extremely common but I doubt there is a surefire way to differentiate pure spam and such attacks.
You can definitely "burn" the dust by sending it to a known burn address like 1CounterpartyXXXXXXXXXXXXXXXUWLpVr, 1111111111111111111114oLvT2 , etc. Or else, you can burn it using OP_return which eliminates the UTXO from the chainstate for everyone and doesn't provide additional bloat.
I think the problem lies with the economics of doing so. For some dust transactions, it'll possibly cost more than the dust itself to send and make sure that it confirms. For certain wallets, there are ways to just isolate the UTXO and ensure that your wallet will never attempt to spend it.

How can we burn dust? As far as I understand, the idea behind is to observe transactions which contain dust and see if several addresses sends dust "together" -> in one transaction or to the same address.
What if all the people would send dust to one agreed address?
