I thought the binary mode was intended to handle all plot types,
not just the new "with image".  Or have I got that wrong?
If indeed it is to handle all plot styles, then it suffers from the same
ambiguities as the non-binary form of plot commands.
Simplest case:
	plot 'data' using 0:5 with lines	# y value is found in col 2
	plot 'data' using 5 with lines  # same y value is now found in col 1

If you omit the using spec, it is ambiguous where to find the y value.
So I don't see how
	plot 'data' binary with lines
is supposed to work unambiguously.

That said, I would be perfectly happy to restrict things so that
binary mode does not permit an implicit x-val column.
