There is an ongoing controversy in the UK where the corrupt government is openly neglecting people with ARFID due to sheer incompetence by sectioning them without proper treatment instead of actually using people trained to treat this stupid mental health condition WITHOUT involuntarily committing them, resulting in patents getting abused by grossly incompetent staff.
ARFID is an eating disorder that is pretty much "picky eating on steroids", people with this disorder will not only avoid foods based on smell and even appearance if the food looks gross, but they also struggle to eat stuff based on things such as taste and texture and can find themselves forced to spit out food and can even gag on it, people with this condition are also more sensitive to "food quality" and will not eat stuff if it's not prepared right.
Examples, sorry that all the sources are woke, I could not find anything else talking about this retarded issue:

But this existed before, this is just a new name/rebranding, DSM V consolidating a few things IIRC. Particularly in autism (and most of this is in kids with autism), but also as a thing where kids had a swallowing disorder or issue early on, which even if it was resolved surgically, it would then self-perpetuate as a behavioural issue as the parents were anxious af and reacting to every minor issue, the kid picks up on it, then becomes more likely to gag, which sends the mom into a bit of a panic, scaring the child further... basically they're training/conditioning each other to have incredibly stressful meal times and the kid to avoid eating. Or also just 'severe' picky eating to the point where it reaches clinician significance as you noted, the extreme outliers
these are all things that existed for ages.
