Do we have any evidence systems would use it to format machine generated 
data?

cwm (for is..of) does not use it in output even when it would save 
having to invent a bNode label (one argument for inverses).

_:a is :p of :s1, :s2 .

I'm not disagreeing with the use case but you're arguing in line with 
the style that does not work for me at this late stage - it does not 
consider total impact. This isn't a case of "ignore if you don't want to 
use it".
