While I agree that the resistors arent the optimum solution, the current >xenon wiring is indeed very safe. (It doesn't use resistors at all). In fact the 2 signals that you are concerned about are already "pulled up" to Vgpu and the SMC can only pull them low for jtag. There is no possibility of overdrive whatsoever, and those parts can be left in with no harm.
To that end, xenon users should also implement the new level shifting scheme too, as it is electrically superior, and uses less parts.
For xenon use:
j2d2.7---------j2d2.4 (jumper wire)
j1f1.3---|<----j2d2.1
j1f1.4---|<----j2d2.2

So, I will be rewiring my box with this method when my new 30 awg wire arrives in the mail. If I have made an error in the diagram, please let me know so that I may fix it!
