I changed the title. Although I heard from someone involved that the intermediates really should be revoked in 7 days. Let's wait and see.
Also, given that the underlying cause appears to be ignorance, it would be prudent to take things slow and ensure that this doesn’t happen again. As I said before, the damage is already done—revoking appears to be insufficient here.
If this does actually happen within 7 days, though, I will be thoroughly impressed.
