Could have been higher, if it weren't so cumbersome to configure.

If you honestly want Tor IPv6 adoption to go up, you should stop treating it
as a second-class citizen in Tor, i.e. firstly remove the need to have a
static literal IPv6 in the config. Not a single other network daemon requires
that. And many home IPv6 allocations are dynamic, so users with those can't
feasibly set that up even if they wanted.

What was it, "it's tricky to autodetect which IPv6 to use"? No it's really
not. Even starting with a simple "ip route get 2001:db8::", then looking at
what "src" you get and if it's a proper global one (in 2000::/3), and try to
retrieve something from the Tor project over v6 to confirm that it actually
works. Done.
