try very hard not to step on anybody's toes in my ignorance

I've yet to see a project without having bugs, regressions or changing functionality during its development. It just doesn't make any sense to me, sorry.

anyway, not sure why the number of tracks i contributed to vdrift should decide your involvement in vdrift

Let's say I had some code to support track object instances and rigid bodies. But it would require rather extensive changes to the track files breaking your current workflow and eventually introducing some regressions. I don't see it happen given our differing points of view.
