I see, Thanks again for breaking down some of these arguments.

Obviously I'm not a Core developer, so I just wanted to know what's going on as I can only look at it from my own view and usage and wonder if I missed something.

Now I feel like this whole debate in nonsensical.

if I opened Bitcoin Core QT and on IBD a pop up asked:

"do you want mempoolfullrbf=0, or mempoolfullrbf=1"

This would be the only way to stop hurting sensitivities. Anyone who runs CLI is going to know how to change defaults anyway.
