I pushed this after some fairly minor changes, directly including the patch to route the horizon computation through tableam. The only real change is that I removed the table relfilenode from the nbtree/hash deletion WAL record - it was only required to access the heap without accessing the catalog and was unused now. Also added a WAL version bump. It seems possible that some other AM might want to generalize the prefetch logic from heapam.c, but I think it's fair to defer that until such an AM wants to do so.
