I'm very much looking forward to WebGPU becoming mainstream, as there's definitely more performance to be had. However, the use cases for WebGL aren't quite as bad as you're making out. I'm CTO of a business that's core offering (since 2016) is selling real-time interactive 3D real estate models. Browser support is decent, our models run in mobile browsers alright. The models certainly run slower on mobile than they do on a gaming computer. However, on-board Intel graphics frequently found in enterprise laptops can be worse performing than a decent mobile phone. Sadly my preferred browser, Firefox, has (by quite a significant margin) the worst performance of all mainstream browsers. It's more CPU bound than GPU bound though.
