I’m asking that question since I’d like to get a sense if your concerns are more about conservatism (not wanting to change behavior), stability of G1 or otherwise.

That is a fair question. If the G1 were as stable and mature as the Parallel collector is today and the Parallel collector was as stable and mature as the G1 is today, I don’t think I’d change my opinion to make a conservative decision.
