Our Commentary ​

Okay, pnpm doctor is a huge win for developer experience. We've all spent too much time debugging environment issues, and a built-in diagnostic tool is just smart. The expanded peer dependency support is also a nice touch, making things more flexible. It's these kinds of DX improvements that really make a difference in daily workflow.
