The biggest advantage of pixel art is that it takes up less resources to create a solid retro type game. Animations suddenly become a lot easier as it relies on the abstract nature of putting the imaginative efforts to the users. By removing these artifacts, you essentially defeat that purpose. Animating vectors would take a lot more time to create something that seems professional, mostly because you have to be far more detail - analogous to moving from 2d to 3d. I personally don’t see the use cases for this in gaming.
