--- Comment #26 from Sandro gui1ty@penguinpee.nl --- I have submitted two more PRs:
1. https://src.fedoraproject.org/rpms/mlpack/pull-request/14 - `mlpack` is a leaf package with no dependent packages 2. https://src.fedoraproject.org/rpms/python-devicely/pull-request/4 - `python-devicely` is a noarch package, but for some reason it didn't use `BuildArch: noarch`
Once these two are merged, we should be good to go dropping i686 in rawhide.
