question about deferred patches

[Jamie Taylor]

I have a question about the patch management system.  The description
of the "deferred" status is:
> This means that the patch is deferred because of code freeze for an
> upcoming release. You need to either resend after the release, make
> the patch less intrusive, or make a convincing argument that it needs
> to be included in the release.

Why do patches have to be resubmitted after a release rather than just
marking all deferred patches as "New" after the release?

Thanks,
