The obligation to enable it has been shifted to its various consumers (e.g. gvfs, flatpak, appimage, sshfs).

-- The [Grav CMS][https://getgrav.org/] package `grav` is now deprecated and users are directed to `grav_2`.

   This option was previously removed with NixOS 25.05 due to an upstream Plausible change making declarative admin creation more difficult, but this change re-implements the admin creation directly.
