I'm having trouble parsing the comment, but i don't really see why the fact 
that some users may be changing linkage
should deter us from having the right default. If some users change linkage, 
then regardless of where this is dealt with,
the users will have to be adjusted, just a different set of them. It seems to 
me that fixing the ones that already mess with linkage is the right choice,
not fixing the ones that *don't* mess with linkage.
