I consider it a crucial part of gerrits functionality to be able to amend patches (rebasing them, doing easy fixes etc.) to get them ready to be merged, especially when reviewing extension registration patches for Repos I do not have +2 permissions to. As I have already +2 permissions for some extensions (for example extension-Variables), this shouldn't be a problem.
Is there an easier way to join this group? I do not really consider Gerrit as functional without being able to amend patches.
