Inner layer pads are useful for microwave filters implemented as Kicad
modules, allowing tracks to connect to them.

I've made a quick and dirty change to support the board I'm currently
designing:

The result looks like this (purple fingers are a polygon):

This needs an IsOnInnerLayer function which does not appear to be in
the existing source. Also, using LAYER_TRACKS gives gray pads. What
would be the best way to handle this?

DRC and generated gerbers appear to be correct.

I brought this up in the past on the kicad.info forum:
