The MWI people don't have to assume anything because there is
absolutely nothing in t he Schrodinger Wave E quation
about collapsing, its the Copenhagen people who have to assume that
somehow it does.
It's not just an assumption. It's an observation. The SE alone
didn't explain the observation, hence the additional ideas.

Moreover, MWI DOES make additional assumptions, as its name
indicates, based on the assumption that all possible measurements
MUST be measured, in this case in other worlds.
That is not an assumption. It is the quasi-literal reading of the
waves. It is Copenhagen who added an assumption, basically the
assumption that the wave does not apply to the observer: they assumed
QM was wrong for the macroscopic world (Bohr) or for the conscious
mind (Wigner, von Neumann) depending where you put the cut.
I reject this hypothesis. What I do concede is that in the case of
the Multiverse of String Theory, if time is infinite and the
possible universes finite -- 10^500 -- all possible universes will
be, or have been, realized. AG
OK, but that is not Everett-Deustch "multiverse" (relative state, many-
worlds, etc.).
