It's not irrelevant if you don't have the information that locates

consider the sector where you have some definite information and
then project onto that subspace.
That reminds me of a student asked to find the spot where silver atoms
would strike the detector after passing through a Stern-Gerlach
instrument who started, "Well first you should write down the
Hamiltonian of the Stern-Gerlach magnets..."
The discussions on this list, this is actually relevant.
On this list the advice seems to be, "First, write down the Hamiltonian
of the multiverse."
