Oh sure, plus lots of connectors where there's just not ddc bus at all.
But if we only roll this out for a handful of drivers it's also not great,
that's what I meant. Looking at

$ git grep drm_do_get_edid

there's only very few drivers where the ddc bus is hidden. There's a lot
more where it's not, and I think a big series to tackle those would serve
extremely well to make a case for this sysfs link.
