There is upside to that strategy, if you drop from long list all
devices which have a problem, but problem you can workaround with, you
don't have to build a network.

That appears to support my argument. You have flat pool of prefixes,
the more VRF you divide it with, the less prefixes per VRF?

That is my belief, yes. But I've never tested past few thousand BGP
sessions. Usually there isn't any hard limit, it's just config gets
slow to parse, boot time becomes problematic etc.
