Arch is great if you want to customize your system, but I wouldn’t say it really needs “maintaining” beyond just updating more frequently. (which you don’t even really need to do very often, you just have the option to get newer versions of software.)
I think a more direct comparison would be flying the US flag with a state flag covering half of it.
Personal identity flags are perfectly fine, alongside the rainbow pride flag or just on their own. Just don’t cover over the “everyone” flag with specific identities. That’s like the opposite of the flag’s meaning.
