More importantly the output of those simple scaling algos looks horrible. Admittedly we do have a lot of Amiga games with simple scaling of 2D graphics and they always looked horrible; I agree that hardware accelerated horrible looks may be better than non-hardware accelerated horrible looks but only in that they would eat less CPU-time to achieve the horrible look.

It would be a lot faster than software scaling though.
Personally I like very much the scaled graphics of Outrun/Afterburner/Powerdrift/Galaxy Force.
Anyway, it would be optional. If a developer wouldn't want to use it, so be it.
