I think this is unavoidable for such a big fonts like Noto Sans/Serif
CJK. We already has issue about freeze the computer even without Serif
fonts (#84505).
Even with splitted packages, user still feels freeze when doing upgrade,
so I think splitting due to freeze might not be a good idea.

It looks like we can do some cleanup for them. Maybe after Stretch?

I think one solution is to split the font from texlive-lang-chinese, and
use soft link to put it in properly location so that fontconfig can use
them.
As for fonts-noto-cjk, Google does not provide anything other than font
files themselves. So the font files is the only file format we have, and
they are the preferable source format for source package.
