Whether it's somewhat or fully outlawed, or it's just a case of being outlawed in some areas but not others (not that any of this matters too much for adding a job), the
entry on it in EE2 does point to it being close to thaumaturgy, much as
geomancy is with conjury and, in its focus, astromancy. Nonetheless, I don't think that really poses much of a hindrance, since it's always open to them to simply present the practitioners we've seen thus far as less experienced in the arts than the hypothetical trainer.
Here's the interview, anyhow, and yes, it is rather cut and dry. Still, I'd hope they put aside and preserved concepts from it for future use, if they were good.
