I've not heard of "Tor v3 Onion Networking". Does it exist? Or if not,
are there plans?

Or do you mean just using v3 onion-onion sockets? That would be painful.

If there were native overlay networking among v3 onions, which handled
UDP as well as TCP, that would arguably be a better solution. But you
can't just invent an addressing scheme, because none of the existing
tools and apps could use it. For compatibility, isn't IPv6 the only
workable approach? The IPv4 space is way too small.

Indeed, as discussed in other threads, v3 onion mapping would take a
large chunk of IPv6. And that would mean stepping on assigned public
IPv6 ranges. Or just using a restricted v3 address space.
