It's possible that, during assembly & disassembly, this would work more quickly and reliably than disconnecting and reconnecting cables. Do you need to retension shift cables after putting the bike back together?
No. I use DaVinci cable splitters. Takes about 1 minute to connect 2 shift cables and 1 brake cable without tools--no fiddling required.
I thought about Di2 for about 10 minutes and then I came up with a list big enough to conclude that it would be an extra headache and an extra $2K I could spend doing better things either for myself or others.
