Well I must agree with you, considering the alternative being insecure
by definition or not using ssh-agent. It doesn't seem like that big problem.
(I figured out why it didn't work for me, I'm using some gnome agent, which
likely does not support this or is just buggy)
Anyhow my coworker is quite seriously thinking writing patch, which
would display prompt for sign requests ncluding full path between
requested and localhost, (or for legacy hosts it would just prompt
that 'legacy hosts wants to sign with identity foo', no path, no host
He said it's not exactly difficult patch to make. But how likely it would be
to get something like this integrated upstream?
Today I feel that most people simply accept the security risk, if you have
multiple ssh keys in your 'ssh-add' and you're not using -c, you are highly
likely accessing two or more security domains and are bridging the domains
