It's very common to find artifacts which are signed with an expired key.
This is not a problem for _verification_: key expiry is mostly used to avoid signing with a stolen key.
If an artifact was signed before expiry, it's still valid.

=== Enabling signature verification

Because verifying signatures is more expensive (both I/O and CPU wise) and harder to check manually, it's not enabled by default.
