What's the point of Times New Roman at the end? It does not cover Japanese so
that having it just delays the trigger of next font fallback process, no?

Yes. English Win10 has 0 serif Japanese font, so doing this will:
* Japanese will fallback to next, then to system fallback that uses Meiryo/Yu
Gothic.
* Latin characters can use serif font.
Not really ideal, but at least Latin rendered in serif looks good to me. WDYT?
