Probably. I think not caring is the best bet, though. It's up to reusers to ensure that they comply with copyright law. Maybe they'll be using the logos for fair use -- I don't see why we should worry about that any more than we worry about InstantCommons users reusing CC-BY-SA images without linking to their licenses.
I agree with Aryeh above and believe this is not a technical issue. If someone reuses an image on their wiki, it's their responsibility to check the relevant license allows it, not ours. We most certainly shouldn't be trying to block seemingly illicit uses of images through technical means, because the false positives will get people pissed off, and rightfully so.
If the Commons community wants to move these images to Meta or wherever to make the situation less confusing, I'd encourage that, but that's not a technical issue either. Setting up Meta as a secondary remote file repository would be quite trivial and require no extra coding.
