Such models are certainly inconsistent with the SE. So if your concern is
that the SE does not contain provision for a collapse, then you should
doubt other theories that violate the SE. You can't have it both ways: you
can't reject collapse models because they violate the SE and then embrace
other models that also violate the SE. Either the SE is
universally correct, or it is not.

This has been discussed. To allow for real number probabilities, the number
of branches on each split must be infinite. The measure problem for
infinite numbers of branches has not been solved. It is unlikely that any
consistent measure over infinite numbers of branches can be defined. So
this idea is probably a non-starter. At least other models have a
reasonable chance of success.
