Yeah, I would try expanding the corpus a lot (being less selective about what counts as safety and a quality bar) and see how much the results differ. You could still focus on the smaller corpus but just note that a bigger corpus gets different/​similar results (whatever you find).
I agree that comparing our results with a larger, less selective corpus would be an important robustness check, and we do plan on doing this eventually. We considered defining quantitative criteria for a corpus in the first place but were worried that keywords would give us a distorted result in a somewhat fragmented, interdisciplinary space with a broad range of participants.
