This assumes that every feature update will also have a release name associated with it.  There are already exceptions to the "feature update" has a name rule.  The exception of course being the build released back in July 2015.  It is also true that in that case, it also does not have a version notation (i.e. v1703, v1607, v1511).

I suggest, we make the tags synonyms of one another, only if, additional tags are created for that release.  I also suggest the primary tag notation should be that of the release date notation (i.e. v1703, v1607, v1511).  

If and when, additional tags are created for a major feature release, we can link the synonym link at that point.
