While you're technically correct, 0w10 is a commonly marketed product within the racing industry. See the link below to Summit Racing and you will see 0w10 oils offered by Royal Purple, Redline, Joe Gibbs, Lucas, and Maxima amongst others.
I think it's a little misleading to ding Maxima for offering a non-SAE grade when straight 10 weights are commonly marketed this way to a very narrow racing only market.

I ding them all equally
Making up grades is marketing tripe, nothing more. Particularly now given that the official J300 grading system contains SAE 8 and 12.
So, for example:
The Maxima "RS" "0w10" has a 100C visc of 5.2cSt, making it a 0w-12 assuming it actually meets the 0W-xx designation, which I assume it does.
The Maxima "Extra" "0w10" has a 100C visc of 4.7cSt, making it a 0w-8 "" ""
The Redline Racing "0w10" has a 100C visc of 5.2cSt, making it a 0w-12 "" ""
The Joe Gibbs XP10 "0w10" has a 100C visc of 4.5cSt, making it a 0w-8 "" ""
The Lucas Racing "0w10" has a 100C visc of 5.0cSt, making it a 0w-12 "" ""
Before the new grades were added to J300 these would have all been officially just really thin 0w-20's
