No one ever read it like that until they added that text.
SR4A pg. 179 Noticing Magic
Noticing Magic
Just how obvious are magical skills? Not very, since most spells and spirits have little, if any,
visible effect in the physical world (unless the magician prefers to have flashy effects, or her
tradition calls for it).
An observer has to notice the magician’s intense look of concentration,
whispered incantations, and small gestures. Magicians of some traditions display a more
visible change when practicing magic known as the shamanic mask. The shamanic mask
typically changes the magician’s features temporarily to display characteristics appropriate to
her mentor spirit or tradition—an eagle shaman, for example, might seem to have feathers
or beaklike features while spellcasting or summoning.
Noticing if someone is using a magical skill requires a Perception Test (p. 135) with a
threshold equal to 6 minus the magic’s Force.
More powerful magic is easier to spot with
the gathered mana normally appearing as a disturbance or glowing aura in the air around the
caster. The gamemaster should apply additional modifiers as appropriate, or if the perceiver
is Awakened themselves (+2 dice), astrally perceiving (+2 dice), or if a shamanic mask is
evident (+2 dice).
Do drones "see" a shamanic mask? Do drones "see" any of the non-elemental spell effects? I don't think so. Maybe that's just me then. I read the above passage as a sixth sense perception. But to each his own I guess.
Except for spells with an elemental effect I would think that no drone could see any spell when it is cast. Could a drone see the look on a mages face, yes but it is harder for a drone than a person. A person (any living being?) however, has a psychic sense. They get bonuses to "see" the mana. This is written into the books in multiple locations. Hey, whatever... I play my way, you play yours. This is a trivial thing for me.
*EDIT* This interpretation also goes along with the Dev's separation of magic and technology.
