Comment (by arma):

 Replying to [comment:70 asn]:
 > BTW, do we have plans for deprecating the DirPort completely? So
 changing the client logic to use `BEGIN_DIR` for everything, and
 eventually ripping off the DirPort code from tor?

 I would want to explore the load (cpu and bandwidth) from relay descriptor
 uploads on the dir auths before taking that step. Making all the relays do
 a full v3-or-whatever handshake just to send us their little blob of text
 is not really great.

 That said, maybe we should turn that around and argue for breaking out dir
 auth functionality as a whole.
