I have to read the paper thoroughly but I've come to the opinion that multiple solutions aren't in of themselves a problem if they are incorporated into inferences. A lot of Bayesian inference can be thought of as involving solution spaces, for instance, where you're assigning a probability to each solution. Not disagreeing with you, just wondering out loud if it could be revisited with other methods.
