I'm not a big fan of them on the rear, but for sure on the front.
Mandated back in 2011 they make a lot of sense on the front to make approaching vehicles more visible, especially when muppets don't have auto headlights set, or the car is too old to have them.
On the rear they are optional hence JLR have various configurations. My last Evoque and current BMW both had options in settings to control them.
Personally I'd rather have and see brake lights clearly not slightly brighter than sidelights on as rear DRL's. Yes I know there's a third high level brake light.
As an aside I'm also not a fan of the current voque for car width always on LED strips, back and or front, or pin hole sized brake lights.
