Hmm, yeah that's something that might just happen. But perhaps we can do something about this becoming a real footgun and check out whether we can optimize something with this addon in mind?
Least we can do is check out its source code.
Tim, is that something you'd be interested in doing?

Seems like this theme uses an animated SVG, so that might be what hogs the CPU.
