Postel's Law isn't why we can't correct errors for backwards compatibility reasons.
We can't correct those because backwards compatibility is necessary to creating a global network that lasts decades. It's the railway effect... One simply can't expect every player to update their architecture religiously because they can't afford to, therefore what is made public tends to stick around for ages, and anything that fails to recognize that stickiness (IPv6 is my go to example) does so at its own peril.
