Hmm, I'm wondering if there's a way now to render an SVG (not the full spec) within a service worker e.g. using PngPong with https://github.com/canvg/canvg

Huh! That's a really fascinating library. My gut instinct is still that it would be a heavy lift, though. Without the Canvas API in the middle you'd need to reimplement pixel by pixel drawing of different shape/curves (PngPong literally only draws squares and copies sections of other images) anti-aliasing, etc. etc.

It would be a fascinating thing to work on, but the OffscreenCanvas API is coming to Chrome[1], so I suspect it would end up being a lot of work that would be obselete after not all that much time.
