Per the very first reply on their thread discussing it in their forums, which I linked directly to for the post title:
We’ll NEVER require any verification or identification from the user.
However, what’s gonna happen should the attempts to age-gate the XDG portal screw over alt-init distros like Artix too? My guess is maybe they start blocking regions which force age gating like Arch Linux 32 is doing.
Artix is patching many packages anyway, so one more package patched to remove age stuff or add a dummy interface that always returns 18+ won’t be too difficult.
That’s what Ageless already does, so maybe Artix could implement that officially in their distro by what you’re suggesting?
