Yes! I'm excited about the possibilities of hosting tRPG content as HTML on itch -- including javascript, accessibility via screenreaders and small/underpowered screens, and other things that just aren't possible via the traditional PDF format.
While I happily host free html content on itch, I could also just as easily host it elsewhere? The value-add of using the html5 player doohickey thing is being able to use it for *paid* content. It's a bit baffling that this option doesn't already exist.
