Those vendors likely won’t accept hardsubs, because it would mean 10 video files for 10 languages, instead of soft subs where you get 1 video file 10 languages (10 different subtitle files).
But here’s the other thing - CR could have used the ASS subs on their website and given the less-dynamic sub files to their vendors. You can save a master subtitle file in whatever format you want.
