SVG will very likely take a little longer to render than a base64-encoded raster image. And the Gaussian Blur applied to the simple SVG shapes created by Primitive is probably quite CPU intensive.

Let's run a series of performance tests, ideally on WPT, to compare LQIP raster image rendering performance vs. SQIP rendering performance and also compare CPU utilization.

I have a very big app and do not want to make a placeholder for each screen I would like to provide context to about what is loading. (And also do not want a general 'loading' message). Is there currently a way to change the title/subtitle easily for each ViewController, from the ViewController itself?
