Well, there is an indirect impact on devel.

As I said, it's about what we decide is 'release blocking'. The historic
approach there, and the one that's really simplest and makes most sense,
is 'guided path is release blocking, custom is not'. The more choice
there is on the guided path, the more release blocking codepaths we
have, and the more release blocker bugs you folks get to treadmill.

If, for instance, we ditched LVM thinp and btrfs from the guided path
dropdown, we cut the number of potentially release blocking paths by 50%
immediately. It won't necessarily cut the number of release blocking
bugs by precisely 50%, but it's pretty hard to believe it wouldn't cut
the number at *all*. And I know you folks get tired of the release
blocker treadmill.

Remember, what QA release validation testing ultimately *results in* is
blocker bugs :)
