AOC is pretty low stakes, so it doesn't really make sense to put too much effort into it. For the average person they can get a lot faster by automating all the input downloading/submitting/etc and writing a huge number of utilities in their language of choice than by learning an array language.

Each year probably only a single digit number of people using an array language actively try for leaderboard spots, so if anything it's impressive any of them manage compared to the 100x or 1000x number of python/etc programmers also competing.
