The web platform is over bloated. The proper solution would be a minimum set of APIs and set of reusable by many sites JS/Wasm libraries.
For example, most of Web Audio (thing like filters and oscillators except for actually sending audio to audio card) could be implemented in Wasm making a browser simpler and not allowing to use it for fingerprinting. Also, base64 encoding/decoding, URL handling function, most of canvas code etc. Imagine how less work for browser developer it would be.
I think web needs an “actually standard” library. Something that vendors could ship with browsers but could be also updated to higher version of a site requires it (and cached forever).
That would allow us to not download a bunch of code every time.
