Also expired certificates break a lot of websites… should we disable checking?

Certificate expiration isn't an unanticipated regression. You know when you get a certificate when it will expire.

I don't mean to be pedantic, but not always--see the recent DigiCert delayed revocation issues. I will admit it is rare though and more often than not, you (should) know when your certs are going to expire.

Those websites set up the expiring certificate themselves.
