Pros: May be more productive for Tools that are currently being developed. Much clearer distinction who is driving the tool's development. Tool maintainers may prefer this method as opposed to letting everyone edit and trying to manage it.
Cons: If Tool maintainer abandons the Tool, we need a process for allowing folks to take over maintainership. This could be a community bottleneck.Wiki model (Everyone can edit, votes are taken when there is a disagreement on an edit)
Pros: Everyone can edit so there is no possibility that a tool would be abandoned and willing individual would not be able to take over gardening the tool.
Cons: Everyone can edit... all the voting may be a slow way to develop quickly... maybe.
