This department has participated in regional and international programming contests at tertiary levels about as long as it has been possible to do so. One of the major problems for the organisers of such events is ensuring that working environments for all permitted programming languages are installed (and compatible) on the machines the contestants will use. These days with things like Docker it should be straightforward to set this up once and just push it out to all the machines, but it was not always so. With respect to schools, the sad fact of the matter is that school IT syllabi are often set without the input of any really clued-up programmers. The NZ curriculum was revised not that long ago, and we had some input into it, as a result of which I *think* Python is used in some classrooms. I remember one programming contest where I was supposed to be a local judge, but was ever so glad that nobody needed me, as I spent the entire period *trying* to write and run "Hello World" with Visual Age for Java, which I had never previously seen, and never wish to see again. Pity any contestant who hadn't seen it... So, if we want Haskell (or F#, or whatever) allowed, - it has to be taught by enough schools, - we have to make it easy for the organisers to install the same environment that the pupils will have used.
