If you’re downloading large files (so large you’re concerned about an in-memory tmpfs) to boxes that you don’t own, stop just leaving them around in the first place.
Sure, /tmp is cleaned on boot. But if the host is rarely rebooted it’s pretty inconsiderate to just leave enormous quantities of unneeded crap lying around in shared directories.
/tmp isn’t supposed to be a garbage dump. It’s supposed to be for data that’s actually in use but transient or relevant to running processes. You’re still expected to be a good citizen on shared hosts and clean up after yourself when you’re done.
