I’ll try give an explanation as to why this is not quite as simple as people expect.
Inside Paratext itself, this would be a fair bit of work - requiring many places in the code to be updated to the new behavior. For the most part, the changes would be straightforward, but would require touching many different parts of the code (checks, notes, navigation, view layout, saving, etc.). The only thing keeping us from doing this is probably the time and the priority level (i.e. is it worth the time to do it when it means pushing off other work?).
But the biggest problem is everything that is not Paratext that depends on this behavior. Our users may not realize it, but the low-level Paratext code is shared by other applications (Mostly developed by SIL. e.g. PTLite, FLEx, HearThis, Glyssen, etc.) to allow them to read and process Paratext project data.
We could probably avoid changing the low-level code and not affect other applications, but this would probably result in more of a hack in the Paratext code than a good long-term solution. Barring the hack approach, some (or all) of those applications would also have to be updated to handle the new data processing approach.
