Nice idea. Like a personalized vanguard index for open source donations.

If this takes off people will be inventivized to make lots of small dependencies that are likely to be needed in tier 1 (or tier 2).

The trick will be to find a bug in a first dep of webpack for example, fork it and fix some bugs there then convince webpack to switch to you.

Algorithmic decisions can be gamed.

I suggest instead the app lists the deps, and you choose how much to give each one.
