The people who make a Linux distribution for Apple Silicon Macs are proposing this convention for disk partitions so that multiple operating systems can coexist and be recognized by the OS chooser at boot.

It’s not about the number of cables, but the number of cable types. The combinatoric explosion sucks. I’ve got cables for A-to-B, A-to-mini, A-to-micro, A-to-C, A-to-Lightning, C-to-C (some capable of TB3), C-to-Lightning. Apple already went all-in on USB-C with their laptops years ago, to the extent that they ditched every other port for a while. The sooner they do the same on the iPhone, the sooner we can leave behind the inconvenience of having the wrong cable or lacking a dongle.
