Hey Reuben,
many of the parts you mentioned are available in the Lego Digital Designer (LDD), I think. It is possible to convert them to LDraw:
11129.dat - Minifig Headgear Mask Lion
11233.dat - Minifig Headgear Mask Wolf
12549.dat - Minifig Headgear Mask Eagle
12550.dat - Minifig Headgear Mask Raven
12551.dat - Minifig Headgear Mask Crocodile
But they need to be cleaned before they are worth it to get on the parts tracker. Currently, I do not think that the community has the capacity to keep up with LEGO. Many of the new parts are quite complicated. I can also imagine, that some of the part authors do not like to use data from the LDD.
