This mechanism is also what recently broke all HP printer drivers on macOS.

HP accidentally revoked their certificate, and since macOS automatically checks it before loading code printing and scanning with my HP printer no longer works.

My mom called me with the same issue. She didn't do anything, but all of the sudden her printer stopped working.

There is no way I know of to override the accidental revocation.

Installing updates from Apple and HP didn't help.

Online certificate revocation is a really bad idea for desktop software.
