Musically speaking, I never really understood the point of knowing the notes on the fretboard. Scales, intervals and chords are waaaaay more useful to know. But I‘m self taught, so what do I know?
To me, it's easier to learn a song this way than by reading guitar tabs or notes.
I think it is why so often I hear people play and the strings aren't even tuned. "Who cares, it is just numbers on a finger board game." mindset.
No one on any other instrument ever would say musically, who cares what the notes are.
I see fretboard orientation as relying on multiple techniques: 1. Notes 2. Intervals 3. Scale patterns
Notes are not the only way to orient but they're a start. I'm planning on adding more modules about intervals pretty soon
