To everyone with complaints about the new "Shortbread" styling, I agree that it's not perfect but that's kinda missing the point. The real story is that vector tiles have the styling applied client-side so anyone can tweak the look with a little javascript.

The prior raster tiles have the style baked in; if you want a new look, you need to generate a new image. So each map publisher ends up running their own data and server infrastructure just to tweak the style.

The vector tile approach means a single (cacheable) asset can be used in many different maps. Huge win. If you don't like the style, you can make your own without having to literally download the planet.
