The idea of Declaration is that vendor just states that his product... 1. compatible with XX, 2. has manual, 3. is a module, etc... They may as well state negative answers to those. Moderators only need to have means of verifying declared information. In many cases this won't require a download. So, I can see a system where Vendors would give their products for download to moderators voluntary, or on request, or pro-actively. Maybe we'll just add a posting option like "allow moderators to download" see more and "allow supermoderators to download".
