Do Mac OS apps stop working if your Mac Developer ID Application cert expires?

[Tony Trivia]

Hi,

Anyone know what happens if you let a Mac Developer ID Application cert
expire? (I'm thinking of apps that are NOT in the Mac app store, but are
distributed directly to users.)

I've heard if this cert is revoked, that can block any apps from running
that were signed with that cert. Just wondering what the effect is if the
cert just expires.

Thanks.
Tony
