Question: will carriers accept IPv6 advertisements smaller than /48?

Most of the carriers I've seen won't accept anything smaller than /48. You have 4096 /48s to use in your /36. The bigger concern for carriers/ISPs
is IPv6 routing table bloat from carrying lots of small individual
advertisements.
