Being a webapp and adding GPU rendering are not orthogonal. Figma for instance famously renders it's UI in WebGL.
While I mostly agree that creators of today's web forget that there are a number of simple techniques to render fast pages, there are also a bunch of places where the HTML+CSS+JS web technologies serve us poorly.
* Content Editable is a terrible editing canvas
* Dom and CSS are pretty terrible core animation primitives
* DOM and CSS make for pretty poor interactive graphics capabilities
And in these cases WebGL offers some interesting alternatives to explore.
