MWI is not even considered because MWI does not output a string that begins with the observed data, i.e. MWI will never be found when doing Solomonoff induction.
The same observed that produced Copenhagen and de Broglie-Bohm produced MWI. You acknowledge as much when you state that Copenhagen extends MWI with more axioms. The observation string for MWI is then identical to Copenhagen, and there is no reason to select Copenhagen as preferred.
