The ABC team have forked off BCH, but Mark Lundeberg who made the proposal works for BCHN now, so there is a good chance, if people ask BCHN nicely :-)
If they do resurrect this,
it should specify _absolutely_
that only OP_RETURN transactions are acceptable for this feature.
Or, perhaps, only the OP_RETURN component is zero-fee.
Nah...you can just put a cap on how many txs pr. block can be 0 sats. That is how it originally in the Satoshi Bitcoin node.
You can also make more sofisticated schemes like if a coin has a certain coindays-ago, it should free to move.
This would be ideal. Regular users making occasional purchases should never have to think about fees, blockspace, mempool sizes, etc.
