> that "lockfiles" are an NPM-specific feature

… they're not, though. Python & Rust both have lockfiles. I don't know enough Go to say if go.sum counts, but it might also be a lockfile. They're definitely not unique to NPM, because nothing about the problem being solved is unique to NPM.

OK, but to me a "lockfile" is a file whose existence signals that some resource is locked.

When I saw the title "We shouldn't have needed lockfiles", I expected something about preferring some other mechanism for resource locking.

More generally, I see a lot of articles that talk about an issue in some language or framework that don't mention that context. Just adding "JavaScript" or "NPM" (or whatever) in the title or near the top of the article would be very helpful.
