Is "unprivileged_userns_clone" enabled in Fedora?

Just read the “ungoogled Chromium” documentation and it mentioned to enable this kernel argument to enable the Namespace Sandbox.

I dont care about that Browser at all, but its Sandbox sounds nice. I would 100% invest more time into securing Firefox (in fact I do a bit) but I can imagine enabling this by default would improve usability.

Would there be any drawbacks from enabling this karg?
