Pros: It could maybe possibly potentially mitigate the tx pinning attack that has yet to be proven a real world concern, and could maybe possibly potentially aid users in some extremely rare channel closure scenarios.

Cons: Nobody really knows to the full extent, which is why changes are always bad until they've been in the wild for a few years at least. I speculate this is yet another attack on the mempool, in favor of private (permissioned) mempools. Effectively this is removing a spam protection for no material gain.

Given the dramatic article attacking anyone with any rational thought on the subject, by one of the dumbest MF's in Bitcoin who seems to get paid to do exactly that over and over again, and the fact that the original proposal is from a known bad-actor salaried dev, would seem to justifiy my existing position of never running the latest versions of Core, and that we desperately need "LTS"-like versions of Core and LND to ensure bad changes are relegated to a smaller portion of the network.
