Yes, even if it is an issue for birds, it would actually be really helpful if hybrids were included for plants.
One issue I encounter is with hybrid cultivars that look very different from other species in the genus; some of them also self-seed fairly readily, so observations of wild/feral specimens are not uncommon – it isn’t just a question of exclusively non-wild garden plants not being recognized. A couple that come to mind here are Erysimum x cheiri and some varieties of Viola x wittrockania / Viola x willamsii. Because the flowers are so distinct from the wild forms, the CV typically fails to recognize their affinity with other species in the genus and the suggestions it provides are often not even in the correct family.
