... I don't agree. Ideally the DRC would also be "net-aware" (aka
"connection-aware") so that it could have net-specific design rules, as
well as verifying that you haven't shorted any nets together. It would be
nice to be able to set different clearances for high-voltage nets, or
different minimum trace widths for power nets, for example.

Presently we do have the connection checker to check for shorted nets, but
it's not part of the DRC. Hence the suggestion in the default DRC warning
to explicitly check the connections. Someday the DRC will absorb this
functionality.

In terms of priorities, when I reworked the DRC I wanted to make sure that
it did what it already advertised accurately (which I believe it now does).
There is still a lot more work to be done here, and I believe that the
infrastructure I've put in place should make it easier to expand the DRC in
the future. However, presently I believe that there are other priorities
that are higher.
