So what is the current view people hold about its validity?

"In the context of the many-worlds interpretation, the Deutsch-Wallace [18, 19, 20, 21] and Zurek [31, 32] derivations of the Born rule are arguments of this type, where the quantum stuff is simply the wavefunction. ... A subjective Bayesian analysis of noncontextuality indicates that it can only be derived within a realist approach to physics. At present, this type of derivation has only been carried out in the many-worlds interpretation, but I expect it can be made to work in other realist approaches to quantum theory, including those yet to be discovered."

"In what sense are there probabilities

Sebens and Carroll http://arxiv.org/abs/arXiv:1405.7577

"However, there are serious objections to the approaches already explored and many remain unconvinced, so we offer this derivation as a novel alternative. We seek to provide an epistemic - as opposed to a decision-theoretic derivation of the Born rule ... This approach shares formal features with Zurek's (2003a; 2003b; 2005) argument based on the idea of envariance, while offering a clearer explanation of the way in which probabilities arise in a deterministic setting."

Wallace http://arxiv.org/abs/0712.0149

"Subsequently, I have presented various expansions and developments on the proof (Wallace 2007,2006c), and Zurek (2003b, 2005) has presented another variant of it. It remains a subject of controversy whether or not these ‘proofs’ indeed prove what they set out to prove."
