I'm not sure about the "question nobody asked". Bluetooth is perhaps a gimmick, but in all seriousness an electrically actuated derailleur is a blessing for anyone doing audax / long distance. I have my wrists damaged enough from sitting at a keyboard all day. I don't have to add to it whenever I need to shift gears on a bike.
I see the point of it being a potential e-waste in 10 years, but I'm not sure the mechanical route was much better in that respect (looking at you, shimano shifter-derailleur-brake compatibility table that currently runs a few pages long even before adding all the Di2 stuff)
BTW - "what" do You need a 48-spoke hub for? Are You building cargo bikes in Your spare time? I'm not trying to be snarky - the "all our bikes load limit is 120kg bicycle included" has long been bothering me as well (100kg rider), so... kinda curious about Your side projects
