I have gotten a couple of requests for this; it does complicate the code 
and (and this is realistically speaking much worse) you risk driving the 
monitor in a mode it doesn't have, especially if the BIOS doesn't 
provide EDID information (some BIOSes don't, but it does mean relying on 
more.)

I would like to see a strong use case for this before putting it in, but 
I'm not ruling it out, either.
