Good point. I have taught classes using DrRacket, so I suppose what might be needed is a web-based interface as well. I see similar limitations with Swift Playgrounds. They are great as long as you have a Mac, installed XCode, etc. I don't want to say it was a struggle to get students to install DrRacket, but a web interface like Observable, maybe Pluto, etc. is hard to compete against
