An example of this from my experience: I was working on a side project and ended up doing 2 major version upgrades on a core JS library (maybe routing?) before I even completed the MVP. Definitely not what I wanted to spend my time on at that point.

I believe Deno links to dependencies directly so that you can still rely on old(er) versions, but not sure it would have helped in this case.
