By cooking down the prefixes you unfortunately lose topology information
which might be a bad thing, and at the same moment disrespect the site's
wish to how it would like to be routed. Another bad thing, if you think
of companies/sites paying for the entire network in the long run.

Apart from that, IMHO cooking down the prefixes only buys time, but does
not solve the problem. More people will multihome, and with the current
mechanisms and routing cloud, they have to do it by injecting prefixes.

I'm not sure whether this hasn't long become an architectural question
and should be moved to the (new) IETF arch list. Opinions?

Yours,
        Elmi.

PS: Btw, anyone can give me a hint on where to discuss new ideas for
    e.g. routing schemes (and finding out whether it's an old idea)?
