Think what you're saying though, op. When should this 'telling' take place? At school? Somehow in your 20s before most people have had kids? Early pregnancy?
The info is all there for people. You just didn't want to look into it. And to be honest, once someone is pregnant, they're going to give birth and that entails risk. Warning of risks could just stress them out (which is bad for both health and prospects of easy birth).
C section seems like a good option because you wouldn't have had the complications you have. But it comes with its own risks. My c section left me so shaky that I couldn't hold my baby when she was born. I felt totally disempowered by being surrounded by people as I was cut open on a table. I had a long labour before that so was exhausted. Caring for a newborn on top of major surgery is no joke. Looking after a toddler and newborn would have been even less fun.
There's no perfect option. You're thinking 'wouldn't it be good if I could have avoided the negative impacts of my birth experience' and yes it would, but a c section can also be hard in different ways. Pain, wound infection, harder to breastfeed, longer in a hellish postnatal ward. Not to mention higher risk of baby breathing difficulties (vaginal birth squeezes gunk out of airways) or having other organs being cut during delivery, internal scar lesions, higher risk for future vaginal births as scar can burst open during labour, impact on baby microbiome, etc.
I also found vaginal birth gave me a massive positive hormone rush once it was over, whereas with c section I felt flat and awful.
There are probably things you could do now to safeguard your health in old age, it's not that nobody tells you, it's just that you're busy and don't care much until it affects you. Same with birth. If you're not pregnant or trying, you don't care.
