I understand that the patch adding this functionality is currently in mm-nonmm-unstable. My concern was primarily adhering to the documentation, which suggests keeping the kernel configs pruned of unused options to avoid confusion for those running selftests. However, I see your point regarding the churn. If you prefer, we can wait until the mm-nonmm-unstable branch is merged into the mainline. Once that happens, if this option remains truly redundant or if the implementation changes, I can resubmit the cleanup then. Does that sound like a reasonable compromise to you?
