It is also unnecessary, because having 2 pixels to the right of each

The difference is with the characters above and below.  When doing a
monospaced "grid" display, the Roman characters will form a reliable
grid while the CJK will be put to the left in their allotted space.

Having them in the middle of that space might be more pleasing, but
again, I think we need some input from CJK users here to see what they

I think aligning to middle is better, see the image below. I manually inserted spaces between CJK characters to align them to ASCII characters. The second line is flushed left, the third flushed right, and the fourth aligned to middle. If we flush the CJK to left, CJK characters are closer to the text before and further from the text after, and vice versa for flushing right. The middle-aligned line looks better. 

And we could perhaps leave this as an option to be specified by the user
(somehow).  I.e., flush left, flush right and middle.  But perhaps this
is over-engineering again.

I can’t think of useful use-cases for flushing left and right right now.
