jessie-backports Release file expiry

Hi,

When this repo was archived, shouldn't it be set not to expire?

$ curl -s http://archive.debian.org/debian/dists/jessie-backports/Release |
grep Valid
Valid-Until: Tue, 19 Feb 2019 20:25:43 UTC

This is forcing users to use "check-valid-until=no" [1].

The wheezy-backports do not have this problem.

I am not sure if "check-valid-until=no" is the right way forward or will
the repo get updated in the future to remove this expiry date. Can any of
you please confirm?

Jain.
