Being a Trek fan, I understand what you are saying. However, in Star Trek ships are commonly referred to as the Enterprise-A, the Enterprise-D, etc., and both verbally and in print in official sources.
My wife wants to retain the name of her ship through various models as she progresses through the game, similar to the various iterations of the Enterprise. However, the game does not allow a single user to have the same name on more than one ship, even if changing the letter designation on the ID number (if I recall). So she will include the suffix on her ship's name to achieve the same result. She will not waste EC on changing the name of her old ships, which she may want to use again (if just for RP purposes) in the future.
While it may not be perfect in the strictest "letter of the lore" sense, it does indeed retain the spirit of the lore just fine.
I don't see a problem with that, albeit it ain't something i'd do myself.
Just thought i'd say that because people get confused. Ships only get referred to as Whatever-X in a more informal way. Just trying to help :p
