A lot of this kink is humiliation, so odds are... it just wouldn't work.
That said, society is now accepting kink to the point LGBTQIAPK literally has "kink" at the end. And governments now realize that making this stuff repressed just means other governments will shake down their citizens and compromise their intelligence.
So... we're kinda en route to that future anyway.
Realistically, people just won't be bothered by it. If someone wants to wear footie pajamas at my office, and a diaper, I don't care. Unless they're sales or interacting with people, big diff.
Children have issues because diapers at school would mean other adults changing them, or them changing themselves. It would not be all sunshine and lemon drops.
Imagine a bunch of dirty children all needing changes at school. As an ABDL with desires in early childhood... ick. No. Just no.
