As you have already mentioned, all the users need to do is to enable the 
CR repository . Or wait until CentOS 7.2 will be released, which will 
happen "soon".
And given that the CR repository contains exactly what will become 
CentOS  7.2 (thus behaving like any regular update), I do not see why 
wouldn't the NGINX users use it.
