Is there a plan to have subspecies in the CV? For example, there are currently 26965 of sambucus racemosa (red-berried elder) but 101 observations of sambucus racemosa melanocarpa (rocky mountain elder), which is a regional variant which is black. If you are randomly selecting 1000 photos for the CV, at most 3 or 4 of those will be melanocarpa, and some of them will show things like the leaves and not the actual black berries. Consequently, in my region the CV usually suggests something not found locally for an elderberry which is black, even though melanocarpa is the only black elderberry in this area. Even if it suggest racemosa based on the leaves, a user inexperienced in the taxa might scroll through the first few photos and decide it can’t be that because seemingly all of the photos have red berries, and click something else. As melanocarpa is now over the threshold where it could be included in CV if inaturalist taxonomy assigned it as its own species, it seems like it would be useful to train it as one.
I’m sure there are plenty of similar examples in other taxa.
