With individual precision resistors and generic resistor arrays being so cheap a single package R2R array is just a labour saving thing which don't mean shit when you've got children and robots assembling your boards, so why would china care.

For some part count saving and likely some advantage in matching over using all discrete resistors you can use n 4 packs of R + 2R to get 4n-1 bits.
