Feature: Your code will run on 95% of all browsers

[quetzalsly]

Requested Update

It would be really cool to be able to test your entire code and then see a small status at the bottom: "Your code will run on 95% of all browsers". If you change one feature it will run on 98%.
The data could be compared to caniuse-lite database to see exactly what features are used by browsers.

Why Is This Update Needed?

Just testing against es6 is not enough, some browsers only have partial support. It would be really useful to have exact statistics of where our code will run and what can we do to make it run on even more browsers without using babel, maybe we are just using one weird feature which we can manually replace ourselves.

Are There Examples Of This Requested Update Elsewhere?

I don't think so.
