Artifacting on edges of polygons

In all versions of Java edition, there is aliasing on the edges of blocks. Since mipmapping was added to improve texture quality at a distance, why couldn’t some sort of anti-aliasing on polygons be added, especially because of the rendering engine rewrite and addition of Vibrant Visuals to Java. It is especially awful when in motion and looking at things far away, where it creates a scrolling and flashing mess.
