Makes sense. Though if one wants security maybe it's better to use something like PhotoSync to copy the photos through FTP/anything and mount the volume RO.
Firstly connections to those API should be encrypted, so parameters such as the filename shouldn't be visible by a MitM. Also, as someone else pointed, you could rename the file beforehand to something neutral.
His problem isn't the part where he downloads parts. Jellyfin queries 3rd party metadata providers, such as TMDB. What he's concerned with is JF sending the filename to TMDB and getting spied on by the ISP.
Personally I automatically label and filter out of my inbox automatic emails, stuff that come often. So my inbox usually only has mails that concern me. And then I handle them the same way as you do: keep them unread till I handle them. Then archive those that are "ended".
Tbh those stuff aren't really intuitive. But, as was my case for instance, that's something that can be "easily" learnt as a hobbyist like us. And when you understand those concepts, at least from an abstract point, my stance is that you can become a better dev/ops/sys :) I strongly advice anyone in the field to at least play a little with Docker/containers to grasp what it is.
Currently it's in the CLI, I just split my compose files in different concerns, and just use a bash alias that uses a wildcard to call them all.
But now as I'm adding a RPi in the stack to add some monitoring and a few light stuff, I'm also thinking of going to Kube. But as you say, it may be tough ^^
