alter hooks seam to not be implemented.

The Read Me and project page both mention two hooks that don't seam to be implemented.

hook_styles_default_styles_alter(&$style)
hook_styles_default_presets_alter(&$style)

After noticing that they didn't get called I did a quick search of the module code and did not fine either module_implements or module_invoke calls for either. Could they be implemented in a way that I don't understand, or are they not added yet?

I'm trying to add a new preset that would be applicable for a variety of file types and it seams that this was the intended use case for these alter hooks. Are they still on the roadmap? for now I think I'll just patch the media modules locally, but
