Yeah, sadly Rohan isn't getting backported. It relies on both a change that was made in 3.0.0 (separating the ro sysmodule into it's own service), and a bug that was patched in 3.0.1 (sm:h, full privileges to any service).~snip~
Or maybe it can't be ported, because the flaw is 3.0.0-specific. They done goofed something in that version, if I remember correctly.
