Does it just mean that the visual effect doesn't look good? Because I could see that.
she presumably moves around a lot and making a light source move around a bunch is probably still computationally expensive
Turning a whole person into a moving light source would be an absolute nightmare. You'd have to either use practical effects (e.g. a dude running around with a light ball then masking them out) or fully model and composite the new lighting into every scene and also composite the lighting onto the character.
They probably attempted it, but the look was off because they didn't shoot the scenes on set in a way that made it easy in post, so they scuttled the idea. What this person is saying is just them saying "yeah, that shit looked weird and reshooting the scenes to make it look right would take months that we don't have".
Accurate Tinkerbell but she's a member of the Unseelie Court and feasts on the blood of Mortal Chuds.

"A viewer would be left uncertain of where the light originates"
Damn you're right, they might be forced to come to the conclusion that it's magic or something
