Yeah a good idea. I was thinking we could make a similar table to compat-table (maybe using six-speed or this) that we could use as data to https://github.com/babel/babel-preset-env so that Babel could compile based on the compiled speed relative to native support. Haven't really looked into in much yet (if anyone is interested, let me know)

Basically, if there is native support but it's not as fast as compiled/polyfilled we could continue to compile.
