Bit streams may not be in raw format, so using 'cat' is not possible.
Xilinx and Altera have their own bit stream "richer" format, that need
to be processed before they are presented to the driver(s). So, a
hotplug helper per manufacturer/FPGA is required. Assuming 'cat' will
be used is too limiting.
Does it make sense to you?
