The AMS doesn’t cause the waste, it’s purging the old filament out of the tool head. The H2D and X2D can print two colors with an AMS without needing to purge and the H2C can do 7 without purging. You still need a prime tower when switching tool heads, but that is significantly less than a full purge. But I believe the INDX has the same restriction.
I do agree though that direct feeding each tool head offers the best experience vs the AMS approach.
I’m glad to see Prius’s catching up to Bambu on the color mixing front, Bambu has had CMYK filaments for a long time and has supported color mixing in their slicer for at least a month.

INDX no longer needs a tower. They say there is 13 milligrams of waste (which they call less than a grain of rice) on each filament change. So a print with 1,000 changes wastes 13 grams of filament. Details:

I'd kind of considered printing a rather small thing (seriously, 3x3x3 cm or so) in grey using this technique (using white and black filament). It told me it'd require 140 (== number of layers) filament changes and it'd take 5 hours. (In fairness, if I wanted to print 10 at once it'd probably take a similar time.)
So... honestly it's kinda silly IMO. If I wanted to mix colors in a hacky way I'd just... wait, hold my beer.
