Each of them is interesting in itself. There are certainly concepts we can
pick from all. Forming the right roles and responsibilities which will
probably be the bulk of this exercise.

Meritocracy may be the preferred model (would love to hear from others).
GitHub contributor tracking may not necessarily be accurate for us - there
is a historic.git on which GitHub does not give out statistics, and more
importantly not all our developers have GitHub accounts for it to even
count their patches (e.g I don't see Pranith on the list). But yeah,
getting the stats is just a matter of tooling.
