Security reasons. It weakens isolation between guest and host. See also [1].

I expect it is using VESA and trusting the virtual > firmware instead. In /etc/default/grub using GRUB_GFXMODE="1280x1024" works, but only for the grub boot menu. I don't know which driver/module grub is loading to achieve that. Other then the GRUB_GFXMODE="1280x1024 change, no other changes. So grub default, whatever that is. Any way I could find out? Probably indeed vesa. (Because other standards available at that early phase don't even support higher resolutions in principle as far I know.)
