path build frames should be onioned at each hop to avoid a bad actor controlling two nodes in a path being able to know with certainty, temporal correlation is hard to avoid) that they're hops on the same path. This is desirable as in the worst case someone could be your edge hop and terminal hop on a path, and now the terminal hop knows your IP, making the path basically pointless.
