I prefer the proper solution over my own workarounds, so I'll happily spend some time getting on the path to the future!
I assume there won't be some unattended-upgrade that will half-update parts of some servers, but that it's a deliberate process that needs to be started, which would be good.
Would it be a per-server process, or a whole estate process? And would it be beneficial to have a few spare servers ready for fresh installs followed by some website-shuffeling?
There's nothing crazy, everything can be turned off without impacting the business, it was mostly tongue-in-cheek from my side, although it might be reality for people running huge Enhance estates with proper customisations.
