Yeah I've seen this and don't really like it. I will forever prefer doing all of my own maintenance and choosing my own oil and filter. It essentially abstracts the lube system into a sealed mystery box, I don't like that. It's like a K-Cup for oil, [censored] no.
What I think would be better is something similar to this, keeps all of the things Nexcel does like pumping the oil from the sump into this cell, but you get to open up the cell and replace the cartridge filter and pour out the old oil and put in your new oil and then put the cell back in. This essentially means that instead of draining oil out into a pan and then pouring that into a jug and recycling that, the car keeps the jug inside and you re-use that jug/cell and it contains all of the disposable lubrication components like the oil and filter. Less plastic waste than Nexcel.
This would make oil changes even easier than they already are. They could drive to a recycling facility, pop out the cell, recycle the oil and filter and pour in the new oil and put in a new filter right in the parking lot and away they go. Or they can do all of this at home and just empty the cell into a jug and bring the jug and the used filter to the facility.
The cell would have a drain valve that they can hook up some vinyl tubing to, to make it easier to drain either into a jug with the tubing or just open it up and let it pour at the recycling facility.
