To be fair, the charging cases (if we talk about earbuds) are a good idea.
That said, with wired headphones I need to charge one device less, don't have to worry about battery care (no matter how much effort you consider this, it's zero with wired) and it's no factor for the longevity of the device.
Also this:
And if you're going on long road trips, just pack an adapter and wired headphones if you're that conscious.
So I need another pair of headphones and an apdapter vs just one pair of headphones?
... Aren't devices designed to only charge the battery to 90% (and report that as 100%), because actually changing a battery to 100% is pretty harmful for it?
Mods that are installed by moving files (which covers most games) work fine most of the time; you'll probably need .dll overrides.
Mods that need certain libraries can be a hassle, or mixed bag (eg. RSMods for Rocksmith 2014 (CDLCs work fine though), RDR2 Mods based on ScriptHook.NET).
Mods that require a launcher are hard or impossible (pretty much anything on the Frostbite Engine. I think this is your best bet with it. Don't know if OpenIV currently works on Linux or if you need a VM with shared folders to use it).
You could argue that people can be identified by their writing style. I have no idea how far you'd get with that though.
