The changes are correct as stated in the official statement. In the first place, Unicode in Japanese, Korean, and Chinese is very old, so when versions overlap, they tend to crash because they can't keep up with the font processing. That's probably why they made these specification changes to prevent that. The current fonts are incredibly well-performing. Because the previous font was prone to crashing. So I don't think this is a bug.
