FWIW, at least in RIPE land, the policy still says
"... by advertising that connectivity through its single aggregated
.. which IMHO requires that you must advertise the aggregate. It may
also be read so that you shouldn't advertise anything else than the
aggregate but other interpretations are also possible.
Personally I don't have a huge problem with people who advertise more
routes like above, but I do have a problem if they do not provide a
single aggregated allocation that will provide "default" connectivity
to operators who do filter more specifics.
