This was significant because it was so last minute. It shows "no matter how far you went, you can always put your mental health first".

I think it's also significant because she's womam gymnast. Generally, they have been pushed really hard mentally. With a lot coming out in my country at least about bullying and other (non-sexual) abuse. Mostly this was focused on pushing them to train harder, ignore pain, ignore feelings, and lose more weight.

In that context, having a female gymnast stand up and say "no I am not pushing past my limits" is a big deal. It looks like a break with the past of mental abuse. Hopefully putting gymnastics in a much healthier place.
