I don't think this functionality allows a nonprivileged user to do 
anything they couldn't otherwise do.  You can create inconsistent data 
in the sense that you can choose not to apply certain replicated data. 
But a subscription owner has to have write access to the target tables 
of the subscription, so they already have the ability to write or not 
write any data they want.
