Claiming a message could be an interim solution if you don't want other mods to approve it - but you aren't quite ready to delete/reject.

Claiming a message satisfies a lot of goals (or "use cases," as Joseph puts it). But it seems irrelevant to the one Joseph is alluding to of mods ignoring a message. If they claim it, they're not ignoring it. ;)
