Progressive corporate taxation could make it happen for reasons other than dodging the ghosts of chemical sins past!
One doesn't want to create a 'snake sheds its skin' scenario where Meta (for example), stuffs all its liability in a spin-off, yet keeps the profits those actions accrued in the other entity.
"Should" needs some unpacking; there's a subjective value lurking inside.
Personally, i prefer economic incentives over coercion. My starting point: there is a degree to which society must govern entities within it.
