 It should be clear that the theory of decoherence is an ideal technical tool if (like Everett) one wishes to identify stable structures within the universal wave function. And, indeed, some of the main workers in the field such as Zeh (2000) and (perhaps more guardedly) Zurek (1998) and Gell-Mann and Hartle (e.g. 1990) suggest that decoherence is most naturally understood in terms of Everett-like  interpretations.[17]  This role of decoherence has been emphasised most prominently by Saunders (e.g. 1993) and by Wallace (e.g. 2003), and is in fact responsible for the extraordinary renaissance of the Everett theory within the philosophy of physics since the  mid-1990s.[18]
