      Certificates shouldn’t expire on a specific date. As they age, they should trigger increasingly painful delays in TLS negotiation until someone looks into the problem and replaces them.

      Respectfully disagree. Certificates should have a half-life, like neutrons

          Like random decay? The mean time will be normally distributed around some time in the future? Could expire in three hours, or twenty years. Make Certbot work for it.

          Per-request decay! At half-life, half of requests fail. That way retrying keeps functionality up. But you are heavily incentivized to fix things!

          Perhaps the universe implemented your idea already 😀😀 Just use neutrons as certificates (for existence of energy sufficient for producing the corresponding particle). 😎

          TLS authentication by HL-PUF - proving possession of a Physical Unclonable Function with a half-life.

          OTOH if client certificate validation required OCSP stapling then does it even need an expiration date?

          You mean one starts with a RSA-4096 key and after a year it deteriorates to a 2048 bit key?

          So basically all the old implementations with sidechannel attacks
