Given that ARIN at least is assigning end-user /48s out of 2620::/23 it would be useful to accept these announcements. If not end-user PI is dead in the water. Some providers might like that. End-users probably won't.
The ideal solution, I believe, is to support filters of max networks advertised from origin AS. This would allow for some deaggregation with some amount of protection, even if peers are not filtering their downstreams. Not sure I've seen this level of sophistication out of IOS, though.
