As far as I know, every provider has relented and will accept announcements on ARIN/RIPE/APNIC allocation bounderies. Even the original Sprint access-list 112 was modified to match the allocations. The problem was people wanted to announce smaller blocks than the allocation, e.g. /24's out of traditional class B/16 space.
