Unfortunately deformities might not just develop during pregnancy but during the entirety of childhood. Even if the risk is gone after birth, building countless circular railways could be too expensive, or unappealing to women who may prefer not to have children over using this thing for several months. The point about the function of gravity and deformity is valid. More realistically, both gravity and mass of the organism are likely to influence deformities, since animals with larger mass are impacted more by gravity.
