That's a shame. If we had a good recomp, it would probably be much easier to create mods.
A recompilation project will never provide that. A decompilation (actually recreating matching source code) would allow anything to be possible, but would take a dedicated team of expert developers a very long period of time. It's already been tried and didn't manage to pick up steam as it's so difficult to do.
Regardless, both are unrelated to this mod.
