This is a good start.
First, to those who say "why not just use Apple Music", the main difference with classical music is how works are organized. First, the composer is far more important for classical music than other genres. Second, with classical music, it's standard to have many recordings with different performers for the same piece of music. Third, with classical music, it's critical to group the movements of a single work together.
Together, this is the benefit of Apple Music. For example, if you want to listen to Beethoven's 5th Symphony, you can find the various performances, rather than looking at tracks for the individual movements. This is also my biggest issue with many classical streaming radio programs, including Apple's own classical radio: they play a single movement, then switch to a completely unrelated work. This can be jarring with movements that were specifically composed to go directly into the next one ("attacca").
As for the iPad app, I'm still puzzled why Apple hasn't enabled it for Apple Silicon Macs. All this takes is a setting in the App Store catalog. Perhaps Apple will eventually release a Mac-native app, but they could have made the iPad version available today. This is unfortunate.
