Many files are cross-linked for many different reasons in GWX.
If you tried to draw a picture connecting all the cross-links?
It would probably look like a young child's first time with a crayon!!
Many times this was done to re-use existing data instead of just slapping in more stuff to load at Game start.
There are many dats and such that were used from many Modders that GWX Dev's rolled into one dat and such instead of many as they used the same textures and stuff.
No need to have 4 dats that use the same texture when 1 dat will do the job.
Other times it was done to place things in logical locations for a particular reason.
It's nice to create new dats and support files for a stand-alone Mod as it makes it mostly cross Mod compatabile.
But for any Major Mod such as LSH, NYGM, WAC, GWX?
Cutting down total files and file sizes is a major consideration.
Had We went on another year or so?
I'd bet GWX would have been reduced quite a bit more in total on-disk size while offering even more cool stuff.
