Publishing as a torrent solves for hash verification (assuming new torrents vs mutable torrents for underlying changes) and ease of sharing (imho).
Torrenting is a great solution as well. For now I just wanted direct download. Thanks for sharing those links!
If you have a NAS and want to back up open weight models with a little more structure than just "download and store" I created this toy project. It's actually working quite well for me already.
