For me, it just seems logical to do it.
The devs are trying to please the C4D users by making many things work as the people are used to from the native settings.
For MAX it might be different, the axis configuration is also different. I'm aware that "not all renderers" use the same normal map format but nowadays, those two setups have emerged as something like a standard for the type of content one wants to create.
Btw, now that Arnold is Max's default renderer, how's the setup there? Was the order changed specifically for MAX users? I'm curious.
If C4D CRN default isn't changed inside or a default checked box for the Y inversion in the shader, then it'd be nice to have a setting in the global preferences or a button to switch them in the materials.
Or maybe, I'll make an xpresso script for that, sell it and sleep on a pile of cash.
