Indeed, for my proposal of net classes defined in gschem clean modular
design should still work. For this case flow of information is from
gschem to PCB. But we should teach gschem that a large net can consist
of multiple connected subnets, for example a 3.3V net, with width traces
from DC/DC-Converter to FPGA, and narrow traces to some other devices.

Then we have to teach gnetlist to process this, and to teach PCB program
to understand it.

I think, if that concept is really useful, then we should try to
implement it.

Painting my house is fun, and it will look really nice. But I think I
should repair the broken roof first, and improve thermal insulation.
But I may need (support of) a craftsman.
