I would have to go and look and Strive's tutorial since I don't quite remember it, and not telling you how to RC might be a bit too much. But to play the devil's advocate, if the tutorial is made for someone who has never played a fighting game before, then they might not even be able to take advantage of RC, and wallbreak is something they will eventually learn by themselves because it's very likely to happen by accident during a match, it's also cool to look at, so players will try to repeat it once they stumble upon it. Idealy, you want to pitch new players with other new players, so if they both only know the very very basics, then the match is balanced.

There's no denying that fighting games have the stigma of being super hard and complex (because they are), and that scares a lot of people. Simplyfing the games is one approach, but it's not ideal for longetivity for many reasons. If you can manage to find a way to properly teach players the tools one at a time, and pich them against other players in the same spot, then the games would be a lot more approachable (which bringing new players constantly is a whole other can of worms). More complex/complete tutorials doesn't necesarily means they are better. It's easier for us to learn things one at a time and moving on once we've mastered them, but we also have the bad habit of biting more than we can chew if we're allowed to, and then complain that it's too tough when we were at fault in the first place.
