My point is that it's not a feature of BGP, it's a purely human convention, arrived at through the intersection of pain and laziness. There's nothing inherently "right" or "wrong" about where the line was drawn, so for networks to decide that /24 is causing too much pain, and moving the line to /23 is no more "right" or "wong" than drawing the line at /24. A network that *counts* on its non-connected sites being reachable because they're over a mythical /24 limit is no more right than a customer upset that their /25 announcements aren't being listened to.
IMO this line wasn't arbitrary, it was (and it still is) a smallest possible network size allocated by RIRs. So it's just a common sense to receive everything down to /24 to have the complete data about all Internet participants.
