Except I'm fairly certain the lore team isn't on bug fix duty. This is something they would have completed early on in the lore development so that NPCs can be named to the conventions(or purposely not). There isn't much I can think of that should cause any changes to such a basic component of the lore.
The simplest fixed, based on comments in this thread, would have been to add a post to the naming conventions thread with the headers for Hrothgar and Viera to show that it will be added. That wouldn't stop all of the comments, but it would at least give something tangible for the community to point to.
^ I'll second that. (Though I would like to get my alts name change figured out soon =) )
