Carbon filters have been deleted. I'm now at ~6200 miles.
Up till this trip to Atlanta last night I had been at 17 mpg for more or less duration of that fun time.
This is significantly different than on the last sampling I provided where 2-3 mpg was more typical.
Note this is still principally across my daily commute route (a mix of urban and interstate to the tune 26 mi one way): no weekend trips (till this weekend) and no track / off road events.
Last night I was in "limo" mode and got 24 mpg from Decatur, AL to Lithia Springs, GA. So I can still drive conservatively and there is nothing "wrong" with the car.
Half way through my trip (~6100), my add oil warning was displayed. I added oil: no drama.
I say all of this to indicate that it is now my experience that how you drive the M5 has a meaningful impact on oil consumption. BUT one sample does not a conclusion make. (Channeling Yoda there.)
Now if someone else would like to repeat the experiment one way or the other (hard to soft / soft to hard) I'd be happy for another datapoint.

So your consumption is 1100 miles/litre as you topped off @ 5100 miles last time.Thats a big thirst to me.
