This is a proposal to modify Request for Adminship in an attempt to improve the process.
In this last case, the consensus is not clear from the raw vote. The RfA is considered closed and no new comments are allowed. The decision to promote is then put up for discussion by all bureaucrats.
When the consensus isn't clear from the support %, bureaucrats decide whether there is consensus to promote. Information that wasn't presented in the RfA can be considered as the goal is to get a comprehensive view of the candidate. The discussion would last as long as necessary to allow input from as many bureaucrats as possible.
While it would be ideal for bureaucrats to come to a consensus, a simple majority of bureaucrats make the final decision.
