Same experience here with a pnpm workspace monorepo. The baseUrl removal was the only real friction — we were using it as a path alias root, had to move everything to subpath imports.

  The moduleResolution: node deprecation is the one I'd flag for anyone not paying attention yet. Switching to nodenext forced us to add .js extensions to all      
  relative imports, which was a bigger migration than expected.

  Compilation speed improvement is real though. Noticeably faster on incremental builds.
