I'll really have to think on this. I don't really see Occult Adventures in the same light as the APG, and there's more than a little argument that several of these would have overlap with the 4e psionic classes, or other PF1e classes, anyway.* Doubly so given it came out in 2015, five years after the APG, which came out only a year after the core rulebook. Pushing things out that far starts to make things like its "Hybrid" classes arguably a "PHB" option as well, since they came out only a month after OA, which would balloon things out enormously.Pathfinder's Occult Adventures was also another one of PF1's 'PHBs', and their attempt to make psionics into another kind of magic.

I'm about 75% no at this point, but I'll keep thinking on it for now.
*Spiritualist is real similar to Summoner, for example. Like, "I can't believe it's not Summoner!" similar.
