I assumed that the threat model includes been given a power brick that is already pawned (maybe has some chip with GSM access and somebody is gonna hack your computer through it or sth, or exploits some unknown zero day). And I would assume that is nation state level of a threat, either a supply chain kind of attack or more targeted.

Personally I have come accross no-data usb cables which I hated, but i see no reason to carry such a cable with me and then carry extra usb cables for data transfer. I am happy enough that the multiple cable problem is mostly solved and I still remember and by no means miss the days that I had to carry a separate charger and associated cable for each device, plus possibly other cables to connect stuff together.
