Why is Fedora 38 missing the essential GPU driver component to have HW acceleration enabled by default?

Does vainfo merely invoking demonstrate that HW acceleration is enabled? I ask because:

  1. I don’t see anything in the output that explicitly states that it is:

  2. …and I don’t see (en/de)codement in nvtop, although github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn/blob/94ad05fd3a8e628f166189cc51b1fb41890dbc82/README.md#improve-performance-by-enabling-hardware-video-acceleration [1] mentions that I should with HWA enabled:
