models are heavy though. imagine sketchfab with models instead of images, is that so useful? Isn't model loading/viewing supported by webXR? currently it seems webXR requires a lot of boilerplate to get it to work, it would be nice to have a simpler way to setup a 3d scene , and html tags should follow. Also , limiting the functionality to 3d models seems odd, how about 360 panoramas, and what about animation?
