After using it for a few days now, I must say I'm kinda growing to like it. My only annoyance is that screen mirroring can't be removed. I don't know how widely used this feature is, but it's something I have never used and never plan to use either. I would much prefer to have something like low battery mode in place of it and not have an additional row with just one or two items.
It's indeed odd that that is locked to CC. Are there others you can't remove? I don't have a developer account so can't try.
