That is VERY reassuring. Just getting my MB 12 2017 m3 to replace my MBPro 2015, just for the portability. If I get a pass thru charging hub, I think even the ports will not be an issue [for me].
The extra ports on a passthrough charging hub will not be equivalent in capability to the extra ports on an MBP. Bandwidth and power mean that tasks like connecting two drives to the MBP and transferring data between them is very flaky. And if you use the one USB-C port for a 60hz monitor you are restricted to USB2.
Of course the MacBook is not really aimed at connecting multiple drives.
You can get more capability with the large and more expensive OWC and Caldigit powered hubs.
