I feel that these discussions are always going back and forth because TB3 is a fantastic docking station port, and a niche port for everything else, so both sides are right. Comparing the 2016+ port selection to the 2015 one is a false dichotomy created by Apple. The straightforward upgrade path would have been to replace TB2 by TB3, like they did on the iMacs.
Exactly. There's nothing wrong with TB3 as a connectivity option, but it shouldn't be the only option.
I understand the desire to make the machine thin, which means the old USB had to go. But taking out the SD card slot makes it seem like they don't want you to have an easy way to add more onboard (-ish) storage space.
