「`moduleResolution: node12` support by weswigham · Pull Request #45884 · microsoft/TypeScript · GitHub」
This PR is mostly just to pack up everything together for reviews over at weswigham#68 (if you're pinged as a reviewer here, go there to just review this most recent stage of development). It's also a viable PR to squash and merge to get everything merged all at once, once reviews and CI are in~
