With plants, a big complaint is that the CV does not include hybrids, leading to misidentifications when people observe hybrids. The staff are currently working on this issue (see: https://forum.inaturalist.org/t/make-computer-vision-include-hybrid-taxa-on-an-opt-in-basis/60160/42 ), but they are working using a “slow, methodical approach” which necessarily means it will take some time.
I’m not an expert at the intricacies of computer vision but to me it seemed that adding back plant hybrids would be a fairly straightforward change. The fixes for inaccurate fungi observations would likely be much more complex, and take even more time unfortunately.
My two cents: although I certainly understand the instinct to be cautious with CV changes, I wonder if the staff are actually being too cautious. Keeping with the status quo is a choice in and of itself, so the risks of rolling out a worse CV should be weighed against the existing problems caused by the current CV.
