It's not weird - every developer wants to 'just code' their features/business logic without having to deal with the pain points of the tech. They choose web tech for their app because the opportunity cost of learning a desktop-native language is the time that could be spent bootstrapping an electron app and getting the product out the door earlier.
It seems like it would be pretty easy to get rolling a feature request for automatic polyfills. I'm not sure if Tauri pre-compiles the js it's handed, but if it does it can very easily check for what needs to be polyfilled.
how (if) important is using as minimal resources on the user's system? (if) Everyone agrees electron is bloated, is it (still) fair to prioritize developer "comfort zone" over actual specs?
