I am firmly in the 3.5mm jack camp because having more options is always better, but I don’t think this is a valid argument. All the devices I find on a daily basis have Bluetooth. For rarer things that you don’t deal with daily such as planes, a £10 Bluetooth dongle provides way better quality than the garbage entertainment system in an airplane can provide anyway, while taking just as little space as a 3.5mm jack’s cable does in your pocket.
