For this community it might be useful to stress that the vast majority of practicing theoretical physicists is not in the least worried about any interpretation of quantum mechanics.
I would argue that the idea instead is to try to make predictions for future experiments. In the case of quantum gravity, especially string theory, these might be thought experiments (what happens if you fall into a black hole), technically infeasible experiments (what would a particle accelerator with the size of the solar system produce), or even completely hypothetical (what if the universe would have eleven macroscopic dimensions) but that does not change the underlying mindset.
When it comes to the interpretation of quantum mechanics there is just nothing left to explain. There is no experiment that decides between different interpretations, so that is it as far as most physicists are concerned.
The ideas in the linked article suffer from the same fate: there does not seem to be even a hypothetical way to test them, and the topic is therefore considered one of philosophy more than physics.
Still, can't alternative formulations inspire new physics? Like Lagrangian/Hamiltonian formulations of classical mechanics making the step towards QM easier?
