I believe we, like debian and others, are waiting for onionbalance
support in the v3 design.

It turns out to be quite hard to change the v3 design to support the
original onionbalance approach. That's because the v3 design added
cross-certification between the overall onion descriptor and each
individual intro point component in the descriptor, so you can't just
take the individual intro points components and put them together into
your own custom frankendescriptor.

See this changelog entry from

  o Major features (onion services, UI change):
    - For a newly created onion service, the default version is now 3.
      Tor still supports existing version 2 services, but the operator
      now needs to set "HiddenServiceVersion 2" in order to create a new
      version 2 service. For existing services, Tor now learns the
      version by reading the key file. Closes ticket 27215.
