Afaik it isn’t an option in SteamOS/HoloISO/ChimeraOS and would require a more “traditional” distro to be used, which does fixes those issues, but now we have other issues, like how those distros aren’t made to be used as consoles, and there’s the issue with Steam Family Sharing (as I understand, you need to be logged with the Steam Account in each system user you wish to share the library with)
