In reply to John.

We didn't say a forced update wasn't possible, just that it would not have helped. They released the update a day earlier. By the time this was asked for, a third of the sites had already been updated. The timeline of updates is something we know very well, and since the exploiting was already underway, forcing it would not move the needle any faster.

It isn't that we can't, it's that it was too late. You need to plan for forced updates before releasing the fixes.
