5 year certs sound like a good compromise to me. We can make client

TOFU issue somewhat rare. Will you set that as a default for your
cert tool then?
Maybe! ;) I *do* plan to finally start work on that tool this week, bythe way.
Hopefully by 2025 we'll have agreed on a way to do smooth roll-overswhich is widely implemented! If that does happen, and it's easilyautomated (which I'd very much like it to be), maybe we can startshifting towards less long-lived keys/certs for a extra peace of mind.
Do you agree with my original recommendation that clients should
auto-accept any cert once the old one has expired? This seems relevant
here. I think it's nice for UX, although I see the obvious security
risk.
In the absence of any other roll-over mechanism, yeah, this seems likesane behaviour for a TOFU client.
