I have wondered about the same (and/or DisplayPort) but with QSFP optics to simplify dealing with the four channels of data.

"Classic" DVI-derived HDMI would probably be trickier because of variable clock speeds and additional data but modern HDMI 2.1 is pretty similar to DisplayPort in that it uses four lanes at fixed rates and sends data as packets over those.

I would love to be able to use standard widely available fiber patch cables for long distance video runs rather than needing proprietary cables only offered in fixed lengths and equipped with enormous connectors that are not friendly to conduit.

Also these days data rates are getting high enough that even normal lengths are problematic, DisplayPort just recently announced that 3 meter cables will need active components for the full 80 gigabit per second mode, which means that a computer on the floor connecting to a monitor on a standing desk will not be guaranteed to work with passive cables. HDMI also recently announced version 2.2 with a bump from 48 to 96 gigabits per second so they'll presumably be in the same boat.
