My interpretation of "possible" as used by certain others is indicative of proposing something as reasonable.
My interpretation of "possible" is not to reject an idea or reported results outright unless I can prove unequivocally (preferably by experiment) that it cannot manifest. Thus QED is possible, but I find it improbable that a theory that generates infinities which have to be removed by "fudging", can be completely correct. It might have some positive aspects, but should not be accepted as the "last word". Renormalistion is needed pecisely because it is assumed that there are "vacuum fluctuations withinthe field surrounding" a solitary electron. This points to a wrong assumption, and therefore I believe that the Casimir effect could have a simpler explanation.
