Talking about not forgetting, you answered after seven years?! :-D

I don't think expiring a signing subkey will make anyone forget
anything. Keyservers are append-only, so the expired subkey stays there,
and many of your peers will also not scrub their keyrings and remove
expired subkeys. Those that do might still keep signing subkeys so they
can still now and in the future verify stuff you signed before it
expired. Expired encryption subkeys don't serve a purpose for your peers
anymore, I think, people who like cleaning up might remove those.

As far as I am aware, the only thing that happens when a signing subkey
expires, is that signatures which have an issuing time after the expiry
are flagged as BAD. All signatures made before the key expired will
still show up as valid signatures by you and your certificate.
