By mapping, I'd mean mapping an EID to a RLOC so that the remote node would know which RLOC should be used to reach a LISP site where the node of the very EID belongs. I don't think this mapping has anything to do with an EID-prefix. Am I mistaken? Another related question might be.... is there any compelling reason why EIDs within a site should better be assigned in the same power-of-2 prefix? If the EID would be assigned to a node, it wouldn't matter much. Or is it to save entry space in the mapping server? The power-of-2 might make sense if the EID is, in fact, assigned to the interface just like the Internet. Then, you would benefit from more efficient interior routing by subnet masks.
