On the other hand, quoting http://plato.stanford.edu/entries/qm-everett/ again:

"Everett wanted a formulation of quantum mechanics that could be 
applied to any physical system whatsoever, one that described 
observers and their measuring devices the same way that it described 
every other physical system."

That is, the measurement paradox *started* the enquiry, but Everett 
looked for a solution that applied generally to a wholly quantum 
world. That, it seems to me, is why decoherence treats relevant 
interactions as de facto "measurements". But maybe that's as silly as 
saying the sun rises when we mean the earth dips toward it.
