I think it's safe to say that it is still considered a fringe theory, as per the multiple references cited. This does not mean that the theory is is untrue, but the rubric at Wikipedia has always been verifiability, not truth.

As long as we're not using what's written in this Wikipedia article as the basis for decisions on editing Shakespearean Authorship Question, I don't see a problem.
