--- Comment #2 from Martin-Éric RACINE <martin-eric.racine at iki.fi> ---
Kinda like "ssh -G" indeed but for the remote host, rather than for how
the local host is configured to interact with the remote host.

I'm asking, because I need to check why authentication suddenly fails
for a host and the information provided by -vvv is too abstract. I
suspect that the key exchange or host key algorithms might have changed
on the remote, and I was hoping for a command option that prints only
that i.e. something like "ssh -Q" but able to query the remote, rather
than what the local "ssh" binary supports.
