Apologies again for not having gotten around to adding ECH
tests to the curl test harness. (That still seems complicated
due to the need for a local ECH-enabled server, but I do have
it on my list.)

Would it make sense in the meantime as a stop-gap to add a test
that checks whether ECH works with [1] and/or [2]?

We've had [1] working online for a few years now. [2] is more
recent (about 6 months old) but produces JSON that's more
easily checked. Neither will go away this year for sure, so
adding one or both could be useful as a temporary thing, but
of course there is a risk of generating false negatives if
I muck up DNS or the VM or something that might disturb other
people.

Cheers,
S.
