Hello hauptmech-

I suspect that the tepid response you have received may be partially a
result of the magnitude of doing this job well.  It touches many aspects of
the PNS router, zone filling, connectivity, drc among others.  Without a
clear, written plan first, it will be hard to say which aspects you are
missing.  I suspect that this is why Tomasz gave you a list of definite
prerequisites to a good implementation that would be accepted.  Now that
these are mostly implemented in the code, you could use them to implement
the next steps that Wayne listed below (Gerber plotting/DRC).

In other words, the responses you have received have given you suggestions
for groundwork that will let us ensure the overall implementation fits in
the project and can be supported in the future.

That said, if your primary interest in Altium import, you might have a look
at the Eagle plugin that handles curved traces by approximating them with
segments of straight traces.  This gets you everything except PNS support
as PNS requires 45º increments at the moment.

On the roadmap, you are correct, it is out of date.  Please feel free to
submit a patch to update them (clear the things that are accomplished, move
missing v5 items onto v6) and then propose additions.  The files are
located in Documentation/development.

Best-
Seth
