> what percentage of React users are making interactive SVGs

Every single app I worked on for the past 5 years did. `mui` icons are SVG for example, and it's common practice to embed SVG as components to avoid the HTTP requests overhead and allow for theming through props.

Most people who embed svgs aren’t looking to make them interactive though. I think I’ve attached event handlers to internal elements in an svg maybe once in my entire career.

Things like the sparkline charts on npmjs (e.g. https://www.npmjs.com/package/npm ) are interactive SVGs. I think they're pretty common for data visualizations of all kinds

Sure, but data visualisations make up a tiny percentage of websites.

That’s a great example of what I’m talking about: it would be the perfect place to bring in a react-svg module. Vast majority of sites don’t use sparkline so the SVG stuff is unused.

That’s not what I’m talking about though: those aren’t interactive. You could dangerouslySetInnerHTML with them (arguably you should, it’s a waste of VDOM otherwise) and they’d be just fine.
