Ok so there are good reasons behind that. "depth-axis" would be a
solution, but it's too long and x/y/z is a widespread convention. I was
just wondering if the GSK API contains other conventions, maybe less
widespread.

An API designed to be commonly used and understood by graphics programmers is exactly the place where you don't want to use obscure, less widespread conventions.
