Not it isn't, the check is built into the upload client, they'd have to implement an on-device storage scanning mechanism. That's a different type of system implemented in a different kind of service.

Not that doing that is hard at all, it's not rocket science and they already have full-system indexing and search, but that's also why this isn't a significant step down any kind of technical slippery slope. The problem here is legislative, not technical.
