It's also probably a godsend for transactions submitted to mempool at a stupid low fee that are stuck in a mempool purgatory.
I can't see it getting out of hand because if the tx submitter wanted top priority, they would just set their fee accordingly. This seems like more a lifeline to help get improperly submitted transactions across the finish line.
The better answer is for more wallets to support RBF

Yea, this is just good if you're using a shit wallet that doesn't support fees/RBF properly. Or even if a counterparty is sending you coins, and they set way too low of a fee.
This is also nothing new. There have been transaction accelerators for many years. Having as an option in mempool.space is a nice tool to have, imo.

So what are the wallets that support RBF? Any link ref?
