I agree with @teellbee. I imagine most newbies (like me) rely on the AI to make IDs on their observations. When someone gives me a different or more specific ID, I often go back to the AI system to see where I went wrong, or whether the organism even shows up in the options. I had assumed that the system automatically adds organisms to taxa if the image is good enough and is not already represented or differs significantly from the images already included. I know IDers can be busy, but especially if they see that they are re-IDing the same or similar organisms, they could add notes to the “More Info on iNaturalist.org” page for that taxon. It could also be a note saying “This [taxon] contains numerous unclassified [subtaxa]” or “This [taxon] is undergoing major restructuring.” Those of us who are not specialists may not be up to searching for extensive keys for each organism we observe.
Thank you to all the IDers out there who help us out!
