Deleted agree about this. Based on feedback on twitter Aria Carley and maybe others in the team do not seem to like notifications.
When I discussed the topic about updating with people from Microsoft they said what I wrote, the lesser updates and "seamless" experience the better. Does not help at all on devices that are turned off in the middle of the TIworker.exe show.
It was not bad in XP, that there is a notification in Systray, could be more logically be a warning in Windows Security center and systray or notification (in practice mostly I see W10/11 notification aren't used, dismissed, or overseen, or silenced. This is quite bad. It is so easy to create notifications even via PowerShell. MVP solutions exist.
We had one systray notification when there are updates missing one for installation start and finish.
