Indeed. 35mm is actually a good archiving format if stored correctly; good for 100 years. No need to continually change tape formats every couple of years.

I've heard for some of the 3 strip technicolor restorations, they scan the 3 individual B&W camera negative rolls separately (red, green, blue) and do the technicolor printing process in software effectively. This can give better results if the final technicolor print has issues.
