Cannot figure out why you are being down voted. YarnV1 and NPM are horrible if you have a large dependency tree. YarnV2 was the first time I enjoyed the package manager.
could it be that in some languages (like my language for example) serious is kinda of a synonym for large?
I've been downvoted at times for using it to mean exactly that, but I can't help it after more than 40 years of thinking in a language different from English.
