Enhance Blender Line Art Modifier's Fill Support

I hope that Blender's Grease Pencil Line Art modifier not only focuses on adding lines to mesh objects but also provides better support for fills. Currently, while filling is possible, the Line Art modifier does not calculate occluded areas, so when there are occluding objects, the fill quality becomes poor. Improving the fill functionality would allow the generated outlines of mesh objects to be used effectively as masks within the Grease Pencil system, enhancing workflow flexibility and enabling more precise artistic control. I wonder if there is any possibility of improving this (in my case, I used Holdout to hide Suzanne's original mesh).
