Interesting to get a glimpse at Google's usage of Typescript and the problems they encounter when upgrading. I imagine scenarios like these can happen more often in Google's monorepo when upgrading a widely used tool, library or language? Does Google use this approach (one set of flags, etc. for a compiler for the entire repo) for other languages too?
