[Request] MDL and Map loader open-sourced

[Zeldaboy14]

I know this is something that apparently is tied to the engine, but is there any way that this could be open-sourced for modder's? Given the fact the bsp format is basically just from quake II (gldsrc at least), it doesn't seem too proprietary to be opened sourced. MDL is a thing of the past too, given the Source 2 is the future for valve. It would be nice for both from the modding standpoint, and those attempting to make their own edits to how bsp's are loaded in (say they need to make changes for their mod to store new things, this would be great).
