Google spends an inordinate amount of money on client software in the form of Chrome, so maybe they could do an additional something, but looking at how their Google docs offline support is implemented, I don't know that there's appetite for that.
Then again there's also Android Studio, so what do I know. (not a lot)
1. You literally can't build something like Android studio emulator on the web.
2. Even if it's thinkable in last 4-5 years due to raising Popularity of web IDE, Android studio was built before that and they chose the IntelliJ platform.
3. Google also has flutter and go.
