It's weird that there's any objection to this, as far as I can tell, being mempool policy. I say that even as I could well imagine myself using mempoolfullrbf=0 on some of my own nodes where I want to keep mempool overhead low.
If you've run a lightning node for any length of time, or even if you haven't and you've sat and watched your tx sat in the mempool for days, it seems a nobrainer.
I've never payed for groceries or anything that wasn't lightning enabled in years.
Thanks.
