My point is that agreement for all targets is not what we want anyway.  
We should make a decision for the GNU system (or for ELF targets in 
general) and then apply that to all targets that are part of the GNU 
system (i.e. all with GNU userspace) (or for ELF targets in general).  If 
an OS maintainer thinks it's bad for their OS, don't enable it there, but 
enabling / disabling on a per-architecture (as opposed to per-OS) basis 
doesn't make sense without a compelling justification.  And we don't have 
many OS maintainers.
