I am not a coach. It is just what I have learned along the way. But it comes from how/when the spine and skull develop. Toddlers/preschoolers are head big/heavy, which increases the likelihood of injury as well. Also, from those who have BTDT for years on years with their daughters, we see how much workout the back gets and inevitably, it will begin to hurt. The less that is done in the younger years to cause precursor damage, the better.
I tried to do a search for you and you are right, there is not much out there now. There certainly was 10+ years ago. Here are a few I found that reference it. Also, CB used to have more threads on it as well and they come up on google searches but the urls don't work anymore because the platform changed their use of forums.
The first url is from CB from several years ago. Be forewarned, Nassar is mentioned several times as he was well respected back then. Also, another member, Dunno, who has since been banned from CB for siding with Nassar and others is also prominent in the thread. Doesn't discount the info. Just warning ahead of time to be sensitive to anyone who may not want to read due to their presence.

This next one is anecdotal but highlights a real life consequence, however rare it might be... Frankly, I am inclined to believe there was an underlying condition that was brought to light from the incident but we will never know. I have followed this little girl since the incident and while she continues to make strides, she still is not able to walk unassisted.
After a routine backbend, a 5-year-old girl is now paralyzed from the waist down.
