Comment (by isis):

 If we're worried that one-hop paths could be used, e.g. by the RSOS to
 upload its descriptor to the HSDir, then using the TAP handshake for said
 upload would reduce the guarantees of authenticity of the HSDir to
 RSA-1024. So yes, since it's trivial to do, there's no performance
 decrease, and nearly non-existent anonymity decrease to exclude TAP, we
 should exclude TAP for RSOSes.
