The blender package now contains the add-ons, but there is a problem with the blender-rpm-macros-1:3.5.0-2.fc37.noarch sub package :(
This rpm no longer contains the blender rpm macros file, it contains a single 3.5MB blender model called 'macros.blend'.
This fixes the 'cycles segfault' on radeon graphics issue for me ([AMD/ATI] Kaveri [Radeon R6 Graphics])
Ok, blender runs, add-ons list seems to be complete, and the rpm macros file is fixed.
