The default value used by by readiness probe http server must be different from the one used to expose the validation endpoints. Having the same port causes the process to fail because two webservers are trying to bind to the same port.
Port 3000 is still used by default to expose the actual validation endpoints, while port 8081 is used to expose the readiness probe endpoint.
By default the Policy Server does not enforce TLS on its main port, because of that using a default value of 8443 instead of 3000 would lead to some confusion (assuming https has to be used instead of http).
To be honest, this is not relevant for the Kubewarden stack, since the kubewarden-controller has always been tuning the PolicyServer deployment to use port 8443. This is more useful for developers and for users that run Policy Server outside of Kubernetes.
