Why not just enable both? Have the control panel be available but more of a power user kind of thing, where the new Settings page is what gets pushed to the average user. Of course it’s more work to maintain both but last time I checked MS were doing alright for themselves and could probably afford it.
Sony has entered the chat. - the shutter button is one of the best features of the Xperia line, for sure. I used it extensively when it was my go-to phone.
