I am not sure what to do about it, but I think the approach you describe
will break the method that Tor Browser just started to use to detect
that an onion service requires client authentication (see
https://trac.torproject.org/projects/tor/ticket/30000 and associated
child tickets). The tldr is that we rely on receiving a new error code
from the SOCKS connect request.
