Replying to [comment:3 gk]:
> dgoulet: What do we need to check for deciding whether we have a single
onion service vs. a "normal" one?
For v2 services (current scheme of 16 char .onion), you can't know. The
service descriptor doesn't advertise such a thing.
For v3 services (>= 0.3.2), the service will put in its descriptor
`single-onion-service` so by fetching it, a client will know.
However, v3 service don't have control port support yet but it is planned
(hopefully, best effort!) to be in 0.3.3. I think maybe a GETINFO command
to ask if this .onion is a single onion (without triggering a descriptor
fetch ofc). Or we could also mention it in the HS_DESC event as well so TB
could monitor that event. Not familiar if TB monitors events but anyway
there are ways to deal with that.
