So that's what I did!

I built a package that generates complete DOM and WebWorker libs with all available web features, which you can use as drop-in replacements in your TypeScript projects.

Lovely to have ts-loader's benchmark harness get a shout out on @typescript.fm - feel free to steal the code! For those curious the performance with the 7.1 APIs is comparable with the 6.x APIs. Before shipping things will likely improve further!
