I'm not convinced this feature is needed at all.  It looks more 
like a Google-specific experiment, and this is not something I 
would like to see in nginx code.

If at all implemented, I would rather prefer adding trailers if a 
transfer encoding used allows this, and discrading them otherwise.  
This is something that anyway will happen if a protocol used does 
not allow trailers at all (e.g., HTTP/1.0).
