It's still a bit relevant for CJK, but not as much as it used to be. CJK have some really complex charactrt that hidpi@2 still isn't enough to present perfectly. For example `國` has almost 6 horizontal line from top to bottom. If you are in dpi@2 and set font size to 10. You need to present a correct line with same width within 3 pixels. Which isn't that 'enough'. Although the information density of CJK character is high enough that it is readable even it is somehow blurry. It is not a good reading experience. And what about non-hidpi screen? I don't even know why people are about to read small text of such complex character without sub-pixel anti-alias.
