I agree, some refactoring/cleanups etc. along with the changes you pointed out above might be worthwhile in the fullness of time, or would be moot if/when `g1_younger_gen_val` and surrounding code were to go away. Thanks for the extra background and the discussion and, yes, this looks fine to me in any case with or without the assert, just to bring the review/discussion to a conclusion from my end :-)
