A significant proportion of 'change management' is pointless, box-ticking bureaucracy and achieves nothing. Just look at any large company's mostly semi-broken IT systems!
Critical infrastructure probably shouldn't be running on desktop Windows anyway, so it's not going to affected. At the other end of the spectrum, if Bob in Marketing's copy of Microsoft Word stops working for a day or two while Microsoft patches something - well, who cares. Hopefully the benefits from a rolling-release system will outweigh that.
Hopefully continuously-updated operating systems will encourage enterprise software vendors to avoid using undocumented/non-standard features, and we'll all be better off.
Incremental changes to the OS may only impose a small cognitive burden of adapting at any given time instead of presenting a seemingly insurmountable obstacle all at once.

Why would such a problem only hit one user, in a place that rolls out an SOE?
This is going to be utter and complete chaos for any organization that performs strict change management and compatibility testing. It's already hard enough to push out normal security updates for some organizations, so having to mix in feature or even kernel changes is going to be a nightmare...
