Doesn’t work when the peer cannot “see” the other transactions. You can’t really give hints that will work consistently.
I don’t buy that premise though either, I was deferring for sake of argument.
It would certainly have to be well motivated. In a future package relay world there’s a few, less so in the near future where 1p1c makes most sense.
edit: last thoughts for now
- something I had thought of and forgot later, but sibling eviction is less important in a “top block” world
- We could decide that later, with “top block”-like solutions that allow relaxed topologies, sibling eviction could be an add-on measure where we do something simple to avoid DoS but perhaps not remove all pins
