Hi,

The damage potential of accepting "up to /29 from 3 distinct /8" is
huge. Please remember that one single /8 can contain up to 2 millions
/29. If today's count of "/25 up to /29" is still quite low, this would
open the way to hell on transfer market (which is self-limiting to /24),
with possibility to go into "portable adresses" land (like in phone
number portability). 

In IPv6 land situation is even worse (let's just hope we won't reach the
200-300K v6 routes very soon).
