Most folks don't really know how to use say Android fastboot or recovery modes either, yet we wouldn't call a device with a wiped system partition "bricked".
Most "bricks" are things like a bootloader getting erased. Reflashing that through the standard process of JTAG or another debug protocol is a straightforward action (after all, the manufacturer has to get the first bootloader on there to begin with). The port pinout and config info just hasn't been publicly documented by the manufacturer, which is what pushes it into the domain of "experts".
