I just agree. It was only 4x improvement.

I think Tony did the excellent answer. I want to highlight the danger of such,
non-coordinated extra filtering done by one ISP. It's really dangerous for the
Internet. On the other hand, no one can allow /32 or /28 prefixes, and no one
like (but everyone allow) /24 and /23 prefixes. And I knew a few cases when such
prefixes was injected into the global network in purpose (it was the only chance
to get the riught result quickly).

In addition, such filtering cause extra usage of the adress space, and I prefere
to see less limits in the prefix sizes because the exhausting of the address
space is real danger (not as the CPU or router memory lack).
