I'm sure that's true for many users. But I also wonder how many users there
are who do care but haven't had a problem until now because they're in
countries where the rules haven't changed in recent years, so it's just
worked.

But let me put it the other way round. If a historical database were
available, why would anyone choose to still use the existing method?
Assuming the new method didn't impose a noticeable speed or memory
constraint, of course.
