This is a sticky issue.

A standard needs to compete in the marketplace of ideas and if it is 
good/useful enough developers will adopt and implement.  In the extreme, 
a good useful standard should be implemented on every platform. 
Unfortunately the definition of "good/useful enough" is a morass that 
defies most logical constructs. Generally what standards are supported 
on what platforms is determined by a political, financial and, once in a 
while, technical evaluation process. To dive into that realm as part of 
a standards definition may be shaking hands with the proverbial tar baby.

I would also be concerned about negative connotations. Statements in a 
standard to the effect of "All major platforms should implement this" 
seems a bit self defeating. It's like a menu at a restaurant saying they 
only use "fresh clean vegetables" (yes, I know one that did this). 
Stating the obvious or expected can bring it into doubt.
