That seems perfectly reasonable to me. I expect balcony railings to be sturdy, they exist precisely to prevent accidents. As long as there is no regulation mandating railings be made of glass, I don't see any problem. I've only ever seen glass railings on the houses of people who can afford to pay someone else to clean them (i.e luxury housing) so I don't see how that makes it harder to build affordable housing.
