Only very involved scenarios came to mind, like "you have connectivity now, but are running on battery, and later you'll have AC power but no connectivity" or something. Cheers
Offline update has disadvantages, but it makes sure that every programs are restarted, thus avoiding strange issues or crashes due to conflicts in libraries versions ([1] is a KDE article that very briefly explaining this). In an another article I could not find anymore, someone from KDE explains that they receive many bug reports where issues comes from system update without reboot (I would also be interested to know what is "many" here).
Indeed, in a perfect setup, system should make a snapshot before updates are applied (see 6. in systemd.offline-updates manpage, note that I have not heard it is done yet by any distribution by default), and revert the changes if the update fails. Anyway, being able to fix a system that has been broken by *online* updates is only relevant if the user has technical skills to do so.
Windows, targeting both technical and non technical users, does exactly this. I did not use an Apple system for years, but I think it was quite similar for system updates. Please don't byte me ;-)
I definitely won't use those OS either unless I have to, but I admit they do many things very well and have competent UI designers. But our favorite OS is still the best because at least we have the choice between online and offline.
