i get you, but this also introduces a whole other set of issues, like "dependency hell", where if you update one package you need to re-jig everything else. Things were just moving much slower back "in the days"
Dep version clashes were a problem until iirc some time about mid-late last decade, say ~2017.
These days it's perfectly solved at some cost in storage and memory, which in entire fairness are lately about as cheap as any other resource. There is also lately a movement in the space significantly away from "taking dependencies," a phrase I quote to highlight its pejorative connotation: presumptively undesirable, however necessary.
If a large language model is satisfactorily efficient for 2025, then to scruple over the disk space and RAM used in the current model of exhaustive dependency resolution employed by modern JS/TS package managers, seems impossible to regard as other than ideologically motivated.
In any case, I took some care earlier to avoid talking beyond the package.json dependency declaration model, in hopes of forestalling precisely this bikeshed. If you want to talk further about things that don't interest me in this context, please find someone else with whom to do so.
(I don't wish to seem rude in this. Only that I have had that discussion too many more times than I can count, and I have long since stopped expecting it to vary noticeably in a given iteration.)
If you mean maintaining separate versions of the same dependency, that doesn't "perfectly solve" the problem because you still can't take an object returned from one library (or something that depends on it and exposes that dependency) and pass it to another library without breakage, which can often be silent and subtle.
