G'day Anthony,
I think Ryan makes good points, but I think the real problem is that becoming an admin is too difficult in the first place. Whether it's making 5000 edits on EN or 500 edits on the commons, these are unnecessary requirements. Adminship should be granted to anyone who can be trusted not to screw things up, and the number of edits has no direct relevance on that point.
The fact that "adminship should be no big deal" should be a Wikimedia rule, at the foundation level. While the individual projects should have some leeway in enacting this rule (at least until the projects are better merged), I find it hard to see how someone who is an admin on the EN project could be denied adminship in the commons project. The reverse is probably also true, but I don't know enough about how hard/easy it is to get adminship on the commons.
I think if people could be de-adminned for obvious abuses (say, unblocking themselves) without going through ArbComm, we'd see the bar lowered significantly for adminship. Nobody wants to risk creating a rogue (or even rouge) admin.
