I would honestly like to avoid any repeating icons and would like to replace all of them (and ready to make them). Also, patterns icons have both different function and different possible resolutions in which they appear (patterns are at 32px and modules basically at every single possible resolution due to DE differences). Also allowing people with different themes to theme YaST differently, because they might want to go crazier than we do. Icons that are allowed to be repeated with that scheme would be device and symbol icons, which would live together with yast-yast2, so they work across modules (because devices are way more universal than module icons).
