Thanks for mentioning this topics; this looks like the topic you mention? It raises some good points that are applicable to this discussion.
Back to the 3 questions raised by OP, it sounds like there is agreement that the answer to Q1 is Yes, separate observations for gall/raised insect (and linked either via comment or “similar observation set”), but no agreement re: Q2 (wild/captive) & Q3 (location) (with strong beliefs both ways and practical reasons for each way) [edit: at least so far].
