The core scaling problem is propagating current fee information (ie. the
dynamic part of route information) across the network.  That's easy with
agreed beacons.  Hard with random beacons.

Beacons are going to get slammed, but it's not clear how bad it is.
Getting slammed from all directions doesn't use up channels; it's only
computational and bandwidth limits.

Their neighbors will want to buff up, too (they'll take some load off
the beacon if both parties route through them).

A semi-realistic simulation would be interesting.  If payments cluster
by geography and some random channels are established by proximity
(ie. low latency) that may take some of load off the beacons too.
