Yes. Given how hard he trashed Finale and Sibelius, I would have thought he'd be less defensive about traditional western notation. But while he mentioned some other systems in actual use and did distinguish between crazy reformers and serious/established reform proposals, he spent most of the video deriding crazy reformers and defending the traditional one. The best he said about "ugly numbering systems" was roughly what most conservatorians say (roughly paraphrased): "that's interesting, maybe it could have some limited didactic use."
