So how is this for a compromise:

If there actually _are_ more announcements than 1024 in any particular /8 
under the control of the RIPE NCC, you implement filtering in such a way 
that it gets down below 1024 again.

In this scenario, as long as the NCC can persuade it's customers to 
aggregate, there are no problems. And if problems arise, it is extremely 
likely that they can be fixed by filtering /20 and longer. That way, only 
the offenders suffer and not the people who aggregate as RIPE tells them 
to do.

A weekly check to see if the number of announcements stays below 1024 
would be quite adequate and not unduly machine or manpower intensive, in 
my opinion.
