Someone should work out a suitably abstract way of defining what these
things mean and create bindings - that's not happened yet. It's not
clear that what's in the code at the minute (which is a very direct
mapping onto Linux stuff) are general things that would apply well to
other OSs and there's not been much demand for this in general,
especially given the tendency for system designs to become more dynamic
and use case driven (or for these things to not be configurable by
software at all making the whole thing moot).
Something that defined a single suspend mode configuration suitable for
all modes would be a bit easier I think, and/or a good work through of
how things are part of the hardware rather than software configuration.
