Studio parts editor, decals, connectivity...

[Travis Cobbs]

The main issue here independent of how will be implemnted the texrure support.

Ldraw library will accept them in part tracker?

No, and frankly, I don't personally feel that they should ever be accepted in the parts tracker as generated by the tool. Having said that, I can sympathize with the tool's author's presumable desire to have all the data in one self-contained file. It should be trivial to write a small tool to read these generated files, extract the textures, and update the dat code to reference the textures (stripping out the embedded texture).
