I'm thinking of something automated.

For example, it's possible to gather some metrics of the usage of libraries from a running process (with strace, google perftools, source maps in javascript...).

It can be a process used by a real user or autotests from the project.

A software could monitor those probes and allow the user to reward the dependencies that:

- use less CPU or energy

- use less memory

- contains less bugs

- ...

If it's automated it will probably be gamed.

Yes but as it is open source everybody will know who game what.
