Having played all three roles in every dungeon...yes, I support this happening. There's just a point in the game where having too low of an ilvl will make a run impossible to do. Honestly, this should have started with the ARR HM dungeons, when you had to have a min ilvl just to even get in. There shouldn't be anymore dungeons that only have a level sync. It's not fair to take a penalty because one party member is in Shire Gear still when you hit Bardam's Mettle. At some point, casual players need to be forced to keep their gear maintained - 'differing play styles' should not even be in this equation when it comes to gear in the DF.
