First: thank you for the code changes!
As to the people part: for a generic call to action, you're right. But
that's not the social dynamic in play here.
For a specific set of people who know each other, trying to communicate
securely, if someone says "hey your key is too broken to use, please fix
it, here's a command to run (which you should check for yourself),
please do so and send us your new public key" ... then that works.
In the generic case, there's a hypothetical reward requiring work now.
In the specific case, it's a case of "you're getting cut out of this
ongoing conversation which presumably matters to you, do this now to get
back in". If the conversation really does matter to that person, then
they will fix their key. I have gotten people to fix various problems
on exactly this basis.
For everyone I am not talking to? Not my business, not my problem.
I can only issue advice and shrug when people ignore it.
Now I just need a sane way to figure out which key caused this. :)
