Differential pair parameters (track width, track gap etc) are not stored in the pcb file.

I added this to v6 milestone because I think we need to consider this in v6.

I would like to co-relate this implementation with this possibly feature

I left TODOs in the code for these, but it will have to wait for 6.0 when (if?) we update the board file format.

While we're there we should also add the two courtyard settings.

Hi Jeff,
What do you mean by "courtyard settings" ?

[Jeff Young (jeyjey)]

Two DRC settings:

Require Courtyard Definitions in Footprints
Prohibit Overlapping Courtyards

Before we add more DRC stuff to the board file, there is currently a
proposal to create a separate constraints file which seems like a
possible candidate to place DRC settings rather than making a change to
the board file format only to remove it later on.
