Theoretically, we can already encode notAfter values as a
GeneralizedTime of up to 99991231235959Z (i.e. Y10K) in an X.509
certificate.

The limitation is purely an implementation issue — not only is it a
fairly safe bet that a lot of software will crap itself on seeing a
GeneralizedTime at all (since for dates before we MUST use UTCTime
instead), but a lot of 32-bit implementations are known to break even
for UTCTime values later than 2038.

So certificates which do this are just not going to interoperate very
well at all.
