I'm currently working on copying the arenas you have here into oxvg. I've raised a draft in case you have any particulars you'd like to comment in.

thanks! I did end up needing to duplicate a bunch of that still unfortunately. I need to store a few other things in the AST, namely line numbers, and some HTML-specific things. Not sure there's a way to avoid that though.

This replaces the posthtml-based transformer/packager/optimizer with a Rust-based one powered by html5ever, the HTML parser from Servo. For SVG optimization, it uses oxvg, an SVGO replacement written in Rust which uses Lightning CSS for CSS optimization.
Aside from being faster, this also reduces the number of npm dependencies to install, some of which haven't been maintained very much over the last few years.
