Thank-you, that looks pretty useful. Prior attempts involved `git blame' in projects' package.json per package. For example, to find when a project adopted React x+1 in which version, to determine the next minimum upgrade (to React ^x.y).

Consuming a package also means following its development alongside one's own. Multiplied by each dependency, it's a commitment to a particular constellation of dependencies. Migration guides and codemods help, but ultimately maintenance requires active participation.

That takes time--often more than what's available.
