discord is too spooky for privacy. Have you heard about discord tokens? I would not include it at least for this reason. And even if I needed to I would choose Lightcord, as it has it's own cool set of features, including themes.
While that's fair enough, I'm not really talking about including it in lite or barebones editions, but rather including discord_arch_electron as an alternative to regular Discord in the contexts that Garuda already offers to install Discord, like in its Ultimate Gamer editions or when it walks you through applications to install after you've first installed Garuda. I probably wasn't communicating clearly. It's just a way to mitigate the performance impact Discord already has, much as how there's an option in Garuda to install Steam with native runtimes (though obviously that has a larger overall impact). Neither should be installed by default on lite/non-gamer editions, but for those contexts where it would be offered up I think it's useful to suggest an alternative that uses native arch packages.
discover-overlay would absolutely be far more optional as even those people who do use discord don't necessarily want or miss the overlay, but it is useful to know that the option is there and I don't think an app store is really sufficient to let you know that there is a way to get that option. Sorta like how Garuda Gamer has things like OpenRGB that most people probably don't actually need, but seeing it there as an option lets people know that it's even possible where they might otherwise assume they're SoL.
