Those are great features and two of the biggest reasons I never bother with Paint. But locking them to Windows 11 and not putting them out on Windows 10 is some Grade A bullshit.
I get why they do it though - any change to win10 needs testing and so on and might not be welcomed by the user base. You can always download a free (as in freedom) image editor, some are even on the Microsoft Store.
Be glad they did not backport all the bad sides of win11...
