I actually got the impression that the Tirs were doing something similar to Sperethiel linguasofts in the earlier 6th World days, but either they gave it up as futile or stopped for other reasons. Nevertheless, there is no reason that someone's campaign couldn't feature elven purists who object to non-elves speaking Sperethiel. Might be good for an adventure or 2.
Remember, the Tir's had some major shakeups in the last several years. As of 2065, all the old Princes were ousted, the border security's softened, imports/exports are on the rise, tourism is up, and they're -- as a whole -- more concerned with foreign relations (and less concerned with being an awesome pseudo-Fascist fantasy kingdom) than they ever have been before.
So
officially, I'd say it's about eight years too late for there to be any formal government-associated programs that are hunting down and deleting Sperethiel linguasofts, or something. But all those old elven supremacists didn't just up and evaporate, so, like you said, there's still some room for diehard elven racists to be trying to keep things "pure" on their own.
