I hardly call speaking Klingon a "superpower".
Remember that novels from the 80's gave Uhura linguistic skills. It's not a recent idea.
IMO the idea of a communications officer who depends entirely on the translator is useless. We've met several aliens for whom the UT doesn't function. What would the TOS crew have done had they met one (in a canon episode or movie)?
And isn't calling nuUhura a totally different person to Uhura Prime completely missing the point of STXI?
