iam glad you tell me what i want, i wouldnt have known otherwise

so as to clarify things, a developer who adds a new option or codec must not
be required to test all combinations and find all legal max/min values, (s)he 
certainly should but if (s)he doesnt then things must work too

i would prefer not to change this without a much better understanding of the 
amount of work this would cause
and as you suggest that you wish to help with the codec-option compatibility
i guess we just need to wait for your API suggestions and patches to see
how easy it is
