It was actually pretty great when I worked for a company making things here in england:
"That needs to move 50cm" meant it had to move exactly 500mm
"That needs to move a foot" meant just kick it over about a foot
It was just an unspoken thing that metric meant precise and imperial was just caveman measuring
TL:DR The stuff the dedicated module is doing will go inside specific Mediatek chips on specific premium monitors
Really weird it's taken this long - I remember reading that the modules were expensive and assumed it was just because they were early generations and Nvidia was still working things out
