I wonder if they ever tried `yarn --pure-lockfile` to avoid updating the lockfile unnecessarily?

Interesting, since NPM has had issues being deterministic since package-lock came to be, and this was one of the main reasons yarn was created.

The fact that yarn has a healthy community, actually accepts contributions, and encourages public discussion is a big pro for me (colored by personal experience).

A small detail from the error outputs that might tell a lot:

NPM error: ~probably not our fault, there might be additional output above

Yarn error: ~an error has occured, here's what you'd do if you think it is a bug

NPM is probably correct most of the time but the difference in attitude felt striking to me.
