On the plus side, not everyone is on 5.15 yet, but those who are using it would
have some issues.  Albeit, with it being an LTS release, the adoption might
increase rapidly.

For instance, I believe that Pop!_OS already ships kernels that are very close
to the upstream, which would hit their current user base.
