The Eclipse Foundation Development Process (AKA, the Eclipse Development Process, or EDP) says nothing about how teams should organize.
The EDP defines a committer role: committers are those developers who have the ability to make decisions for the project (e.g., push commits to project Git repositories and configure build servers). We often say that the committers are the ones with the real power: they’re the ones that hold all of the keys to all of the project resources.
