It could be quite complex to implement though - as so much video has non-standard resolutions (where black bars have been cropped for instance). However you could do a bit of an "educated guess" system - and let people check box at what resolution they wanted XBMC to stop scaling?
You could have different settings for "SD" (i.e. content with a horizontal resolution of 1024 or lower?), "720p" (i.e. content with horizontal resolution >1024 but <=1280), "1080" (i.e. content with a horizontal resolution >1280 but <=1920), "Above HD" (i.e. content with a horizontal resolution >1920)? Then you could have "Output at" options for these four genres (So you could chose to output "SD" as 1080p, "720p" as 720p, "1080" as 1080p but "Above HD" as 2160p?)
I know in researching this the XBMC developers have extolled the difficulties of implementing such a system too due to abnormal video sizes, but as you point out, all it really needs is some good forethought put into what to do with what. Have separate settings for SD/480p, 720, 1920 and 4K that can be enabled or disabled (so if you don't enable SD/480p and 720 they're merely scaled to the first enabled one, 1920), do your matching based on vertical or horizontal resolution (to cover things like 1440x1080p or 1920x800p), and after selecting a resolution, match the refresh rate.
About the trickiest part in my mind is dealing with non-square PAR, so you'd probably have to calculate the "effective resolution" first.
Frankly, I'd be happy with a crude patch that just allowed for "whatever's stock" and "UHD/2160" modes.
