When things like this (or Vello or piet-gpu or etc...) talk about "vector graphics on GPU" they are near exclusively talking only about essentially a full solve solution. A generic solution that handles fonts and svgs and arbitrarily complex paths with strokes and fills and the whole shebang.

These are great goals, but also largely inconsequential with nearly all UI designs. The majority of systems today (like skia) are hybrids. Things like simple shapes (eg, round rects) have analytical shaders on the GPU and complex paths (like fronts) are just done on the CPU once and cached on the GPU in a texture. It's a very robust, fast approach to the wholistic problem, at the cost of not being as "clean" of a solution like a pure GPU renderer would be.
