It will become part of our Root Store Policy (probably with an
implementation deadline).

It would be a compliance issue. Newer versions of Firefox are moving to
not trust SHA-1 certificates at all anyway. Of course, this doesn't
affect people still using old versions, and it doesn't affect email, and
it doesn't consider the effects on the broader ecosystem of continued
SHA-1 use. All of these mean that a policy-based approach is appropriate
in addition to a technical one.
