This can only be useful on the pages like "Select a mirror to download the
file from". It should be made clear that this is not intended for
third-party authors referring to downloadable files, as direct links to
such files are not mirror-friendly.
Also, the user agent UI should make it clear when indicating a "valid"
download that the downloaded file is "considered valid by mozilla.com",
and not just "valid".
I think that another one, probably more useful, attribute for <a> should
be "filesize" or something like that. It would both serve for additional
validation (for example, there's no need to even start the download after
seeing a mismatching Content-Length header) and provide indication about
