Quite high overhead, I'm going to assume that people just generally take
the risk.

I talked with my non-c-challenged coworker about this issue, and he said
he'd write patch for ssh-agent to query for permission to sign. But after few
minutes of looking into ssh, he told me that ssh-agent does not know who
is asking for the signing. Which means we'd need larger change to ssh, and
I doubt upstream would accept the patch :/.
