I thought it already did. When cars wouldn't wake last year due to the Spanish SIM issue, iirc once app had timed out, it still allowed several controls to be activated by Bluetooth. I cannot remember exactly which ones, but I thought the front and trunk icons were available to show that even though the car was asleep, those controls were still active when app in Bluetooth range.
Thanks @jmas , it is very useful to know that this is not just a UK problem. The change in the awake behaviour, confirming what some of us here are seeing is also helpful.

Maybe not front and boot though?
