This uses the EDID info from my HTC Vive to mark it as

I guess I was being naive for thinking that HMDs would come with a
special EDID extension. Google indicates that someone might have worked
on something called HMD-EXT to be standardized by VESA for EDID, but no
documents seem to exist for that.
We had someone working with VESA on exactly that and I thought that had
shipped, but we found the same thing: the extension was never released
and there's not currently a standard way to tag HMDs at the EDID-level,
which is very unfortunate, as you'd want the lowest levels of the system
to be aware of the HMD-ness of a display. You would never want to bring
up a text console on one, or any sort of non-distorted content. I'll
look into getting that effort back on track, but in the meantime it
looks like an EDID blacklist somewhere might be our best bet.
Thanks,
