It's route table pollution if you ask me.. in today's world we have many
IXPs and several tier-1 operators that support RPKI ROV, so when you

already significantly reduce the effects of a BGP hijack.

Not just a route table.

- RIB scale
- FIB scale
- Configuration scale

We just recently learned of a IOS-XR prefix-set limit of 300001 when a
particular customer AS-SET expanded to a higher number of prefixes.

The problem with this scaling is that it doesn't reflect an increase
of revenue but it reflects an increase of cost. CAPEX to upgrade
devices without winning new business and OPEX to manage those
upgrades.

So it is a somewhat selfish solution to a problem.
