^ there's no need for fork to implement the changes but I doubt it's an easy thing either convincing the nodes to change their default settings whenever we want to so I just thought why not set to the lowest possible value and let the users give an option to choose the lowest or priority fee according to their needs. Anyway 0.1sat/vb is more than welcome as well as of current situation.

Orginal spammers doesn't really care about the fee because the 0.1 or 1sat doesn't stop them from minting their useless tokens but I agree that lower the fees the more chance of spamming the blockchain.
