Pin[] clearance off

If clearance on a Pin[] is set to zero, and a polygon is drawn over the
pad, does that have the same effect as "full" thermal? Or does that lead
to rendering artifacts? Should it be a negative clearance, or does that
cause oddments in the code?

It's better to use the thermal tool to remove the clearance, than try
to be clever. CAM software might detect the "zero" width space as
violating the minimum spacing rules.

I "think" PCB handles the two such that the output is identical in both
cases.
