As someone who has been using glitch.com because of A-Frame and was teaching students to also use them together I am really sad by the news. It was a great thing to see students who had no experience with programming to create a virtual spaces in under an hour and after few more lessons using A-Frame in a creative way that I wouldn't even thought off. I guess I would also like to thank you @dmarcos for keeping A-Frame alive. My especially fond memory of it was during Covid lockdowns when my friend reached out to me that he had students of Art University feeling pretty bummed because they weren't able to do a end of a year physical exhibit and if I had any ideas to do a simple site to show the works. What we went with instead was to create a virtual gallery that evolved also in to place where people could stream live performances through the internet and even had a premiere of a CD of a band done there (https://vimeo.com/428814586).
