Different nominator here - I'm not positive, but I think I was the one to nominate the Psych nomination for the eternal tagset last round when people were helping move over nominations from older tagsets. (I remember checking old tagsets for character lists, at least!) I would have nominated it as it was in past tagsets, but I have no objections to the disambiguated version. As you say, it's always best to keep things as clear as possible.
