"is pretty much useless" - Needs bug(s) filed and development work in order
to rectify this problem.
I'd caution against: "is useless, never talk to it again" because ...
ideally we want all the bgp software folk to do the right thing here, right?
 so ideally ov-clarify already whacks "popular hardware vendors" on the
nose, let's make sure the 'popular software vendors' also have bugs filed
against them?

"they are irrelevant" - because of the total DFZ there are X% and of that
set Y% have a supernet with the same path so the subnet 'does not matter'
for routing's behaviour.

right?
