For those using the Netflix add-on, there would be no video. For those using HTTPS Everywhere, there would be no enforced privacy. And the situation was similar for users of password management add-ons, content blocking add-ons, and the like.

It's not like monitoring expiration times of certificates is impossible. Any decent monitoring agent can do that.
