...Previously they were no without explanation, but it never hurts to
explicitly have comments on not doing that, I didn't quickly find
anything nice for ForwardAgent, but I remember the Matrix.org people
somehow avoiding hearing it and ForwardX11 first result was that
StackExchange.
OpenSSH is evil and gives you three not-optimal options to this:
A) trust DNSSEC and don't write known_hosts
B) ask whether to trust DNS, but don't bother telling me if it's signed
C) don't even check SSHFP
I see A) as the least evil, but I wish known_hosts was written.
Alternatively B) should tell me whether there is DNSSEC or not, not
only "matching keys found from DNS" or whatever it says always.
