The beast tribes wouldn't have any influence at all on the languages of civilized society. Very few people would ever have any reason to have any sort of communication with them at all and even then the communication would almost certainly be limited.
At the end of the day, people are going to go whatever direction they want. As mentioned earlier, the Echo completely negates the significance of language IC unless a player chooses for a given PC to not have the Echo. Eorzea has been largely designed in a way that breaks down barriers as opposed to creating them. That said, RP how you want to RP. Even if the devs stated on record one way or the other that something was this way or that, there would still be divergence in RP.
