I like it. As someone else said here, it brings my mind to an alternative web with browsers that had a better default and standardized stylesheet. Oh how I wish for this. Can't just Chrome, Firefox, Edge, Safari all just adopt this one?
Setting up no-CSS sites would be a more sensible thing and we would have less need of Gemini (https://geminiprotocol.net/).
One can dream... Of course, now sites widely rely on a random set of margin defaults, base sizes etc. brought into their websites, so ripping out and changing those wouldn't be quite that simple.
