I would add explicitly the insulation layers, and documentation layers, silks,
etc. I'd add user defined layers as well. I'd add some logic like "XOR this
layer with that, and use it as conductive 2."

Yes. That would be nice. A library is also a hierarchical structure. It
contains the pads, padstacks, footprints. Yes, the padstacks are built up
from primitives.

If I go on, and implement the SQL based file format, it is easy. I defined pad
and padstack tables.

If we go the YAML way, I don't know how to represent that data.
