The number of routing table entries is growing exponentially,
not because of increase of the number of ISPs, but because of
multihoming.

As such, if entities requiring IPv4 multihoming will also
require IPv6 multihoming, the numbers of routing table
entries will be same.

The proper solution is to have end to end multihoming:

Indeed, with the current operational practice. global IPv4
routing table size is bounded below 16M. OTOH, that for
IPv6 is unbounded.
