I spent two years as Chair of the MIPS ABI Group Technical Committee
working on the MIPS psABI and I can attest to how much work it is.
Still, if there were enough of people involved from the kernel,
compiler/library, and appropriate utility communities willing to try to
pull things together, I could see spending time on it.
