While I see your point that you can come up with endless exercises from a few sticking patterns and that it's a good technique builder, I disagree that you only need that page. This argument seems like "You only need the C Major scale - you can derive the rest from that".
Reading and interpreting notes and pauses, different styles of music, odd time signatures, mixed note values like triplets and 8ths, transcriptions, explanations and a structure of how and what to learn in which order... That's pretty hard to get from page one of Stick Control.
Say I'd like to work on jazz comping on the snare with triplets: I don't want to combine the first 6 notes of Exc. 1 and the the last 6 notes of Exc. 7 and play the left hand rhythm with a bunch of random accents to come up with one bar. Also, getting a third voice going is pretty awkward with binary "Right Left" information. If I can remember all of this stuff while practicing, I'm probably advanced enough to no longer need page one sitting on my note stand.
Also, a single lesson costs more than a book, so even if I only get a few things out of one book, I'd say it's worth it.
What I mean is that it’s the only method book you really need. If you want to play actual music, then listen to music, look for drum transcriptions, etc.. You can write your own exercises to help you master specific pieces. I think people are better off learning to write their own exercises than just playing from a method book. I write a lot of my own warmups and exercises, and/or adapt other peoples’ exercises for my own needs.
