No. This is not the main issue, actually. One of the strong incentives
organizations multihome is not to be tied to a specific ISP. There might
be some PA site prefixes leaks, but we do not expect these to be out of
control because a) they do not provide what multihomers want b) it would
be necessary to pay the other ISPs to advertise their competitor's

This scenario is not even on the table. Three times worse than PI is not
going to happen.
The main issue regarding the size of the routing table is everyone
becoming a LIR.
