The post describes moving from an old Yarn version that still suffered from the long, long fixed problem npm had with tree shaking. In fact, their inability to port to the newest Yarn version just highlights my point. Modern npm has solved all of these issues without the compatability problem.

And this is just complete insanity.

That aside, I can see that there's no real argument against pnpm at this point. It wouldn't be the end of the world. I just don't buy saving 20 seconds in CI as a legitimate reason for it.
