I don't think we require strict rules Phil Welch suggested them. It's easy to make a mistake by overlooking a certain discussion or some entry in a log, which could easily make the number of admins dwindle and cause a lot of people to leave the project.
I think we should encourage people to discuss more. If something turns into a wheelwar, all the parties involved should receive a warning not to continue. This would leave good faith unblocking after user requests open without any fears for the involved admin.
Wheelwars usually start when the overturning of a decision is overturned. At such a time any further changes need to be discussed.
