it's time to not have 30 dependencies installed that are a year old and all pretty much deprecated compared to @babel/core and @babel/helper, etc.... .

es2015 is 4 years old. we're all the way past 2016,2017, 2018 and we just use env now.

would be lovely to use this, but it's going in the bin because it requires WAY too many dependencies that i don't need for anything else because everything i have is modern and up to date.
