No. By default and design in new installs System Restore is turned off to not use unnecessary storage space for shadow copies in case user does not want it for instance due small HDD / SSD. This naturally applies both clean installs and OS change (upgrade install).
It's then up to user to enable this optional feature. Or do you mean all Windows optional features should be on and enabled by default? If not, who should be the one to decide which optional features are on and enabled in a new freshly installed or upgraded Windows?
Problem is, you have to manually set the space allocation for System Restore. I don't think MS will remember how much you set it previously. It's based on individual preference. Even if it's turned back on automatically after the update, you still have to go in and adjust the storage allocation.
MS have always had it turned on by default for all other OSs. The average user expects to be able to fall back to system restore when they mess up their system, just like they always have in the past. Changing the rules, and not telling anyone is just plain stupid. MS have enough damage control to do with all their other issues.
