Vector rendering on GPU isn’t hard. The trick is to break paths down into small tiles. Once you do that it’s actually a pretty “boring” problem.

I've been wondering for a while if a retrocomputer with a modern design primarily-vector (GP?)GPU could be viable the more I hear about vector rendering from you, the more it sounds like I should get a bigger FPGA and try it out :P

You should look at what @raphlinus is doing with piet-metal, IMO. Something like that is the logical endpoint of the tiling approach.
Pathfinder is a retrofit of that approach onto the standard GPU rasterization pipeline, but you can cut out steps if you have compute shader.
