Not at all, I was just concerned that aiming for that level might make it
a task with too many imponderables, and therefore prevent even the basic
centralized DDC access being implemented any time soon.

Sounds good. Some degree of extensibility to accommodate new
monitors or model specific features without having to
upgrade X would be a nice quality.

It would be sensible to leverage their work, if they are willing.

I don't know enough about the detail to comment on that. The fact that
information is all locked up behind VESA standards makes it rather
inaccessible to those without corporate backing.
