I'd like to see vector-driven challenges to web standards. For one, we could bring back WYSIWYG under vectors by having grids with "stretch zones" that allow for larger devices. Constraint and flow-based layouts often grow highly convoluted for those of us who need to be generalists (full stack devs). Not every project should have to hire a CSS Sheldon Cooper to get Hello World in the right spot. (SVG and Canvas lack most the Input elements.)
