These are optimised to the level of the materials: Anything that is common between quality profiles with the same material and nozzle gets bubbled to the profile for that material (per nozzle). It doesn't bubble any further (to the variant) because that could have an impact on the other profiles.
This basically only removes settings because where these settings then bubble to is the material profile in the fdm_materials repository. And a lot of settings are just removed because they are equal to the default.

These are now upgraded to version 3, meaning that they will have to increase their version numbers and remove any start_layers_at_same_position settings they define. None of these profiles define any start_layers_at_same_position so it's just the version number then.

Otherwise you get cryptic error messages about settings that may be hidden having invalid values, since minimum fan speed may not be higher than maximum fan speed. The value of the setting with the default settings should be the same.
