::::::From the rationales I'm reading here, I don't think "most" supporters of the current version consider this to be a minor tweak, but arguendo let's assume they do.  A reasonable argument could have been made to these editors that, as you see a large problem with the proposed edit, and as they see negligible benefit, they might want to stand aside rather than support the change.  That's a delicate argument to make and requires a high level of trust among the editors involved.  I don't see any evidence of that trust here, and so I'm not surprised that argument wasn't successful.   
Now that we've moved from persuasion to determining where the consensus lies, no, it is not appropriate to disregard an opinion because an editor considers the edit in question to be minor.  It is even less appropriate to raise this after several opinions have been posted. tc
