Not defending MS, but keyboards already have controllers and have since at least the original PC (probably much earlier than that but I'm not very familiar with old mainframe terminals). Considering how many SKUs already exist for different layouts and the like, this isn't that big of a burden - at most, this requires updated firmware and pad printing layouts, and firmware already changes a decent amount as controllers and membrane layouts are modified for new SKUs and cost-reduction. And it's not like they have to update their existing stock or retool their lines right now, the phase-in will likely take some time.

Also, unless I missed something, I don't think the article says one way or another how this will be implemented. It could be a new scancode or emulate a key combo.
