you have to discuss that with Peter Rolf as he is the one who keeps an 
eye on all possible combinations of settings for pdf standards (and 
checks with validators)

If we can improve this situation, it is only right that we do so. If we can in the process encourage wider adoption of ConTeXt, even better.

an interesting side track would be a set of alternative styles that can 
be used: b/w, larger sizes, opendyslectic fonts, etc ... so, to kind of 
set a standard of producing several versions of one document
