Anyone with any Defender experience remembers the problem of the single large rear door, which created a whole market for the accessory known as a 'gate'. The weight of the door, plus that of the spare wheel, caused the hinges to descend over time, until it was difficult to close. After installing a bike rack for two mtb, I had to install the beautiful 'gate' of the Nakatanenga' and only in this way, by freeing the door from the weight, did I solve the problem. And the Grenadier's wheels are also much heavier than those of the older Defender. Dividing the width of the rear door in two (and certainly with stronger hinges), is an excellent idea, even without having to imagine the convenience for a small load... Plus, as many have said, opening the full width of a door inside a garage it is not always possible... You don't need the intelligence of an influencer to understand the usefulness of the double door...
