We'll see if those shows continue past these upcoming seasons. The production order had gone through already when Google decided that YouTube was going to largely pull out of scripted. I'm guessing it really depends on how many viewers the new seasons bring. But I would not be surprised at all if these second seasons are the end for each of them. Cobra Kai specifically seems like it might have enough of an audience to keep going at least, if not on YouTube than possibly "saved" by some other service.
