For simplicity, I think this can just be: - default VMSPLIT_3G + default VMSPLIT_2G I doubt the 2G vs. 2G_OPT matters in very many cases. If it does, folks can just set it in their config manually. But, in the end, I don't this this matters all that much. If you think having x86 be consistent with ARM, for example, is more important and ARM really wants this complexity, I can live with it.
