It appears this stuff is highly guarded under NDA and not available for anyone, I read the homebrew version (https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain), the SDL2 port and the other stuff and honestly didn’t find anything much interesting, or that makes any difference. Unless you have something properly as documentation to show I don’t think it is reasonable to expect anyone in an open source engine to care about whatever this “special” thing you mention is.
