With JDK-8202286 functionality to put the old generation of generational collectors (parallel, g1) has been introduced.
The idea has been that it could be used to allow use of "cheaper" memory for a larger old gen, in ultimately improving application performance.
However there has been no uptake of this feature and there are no maintainers. Several minor issues with it have been open for a while with no signs of effort fixing these (some issues linked). At the other hand it requires some constant maintenance when developing new features in the heap management area.
I.e. the code has started to bit rot, nobody uses it, and takes time to try to support it in conjunction with new features.
The flag covering this functionality, AllocateOldGenAt is experimental.
So the functionality can be removed.
