I don't think funerals are for the dead people - I think they are for the family and friends and those supporting them - it is their private grief I think a client or therapist would be intruding on - not the dead person. I am an atheist so I think once you are gone - you are gone. The funeral has nothing to do with the feelings of the dead person. In my view, at that point the dead person has none left- so the potential dead person's ok would not be the thing that would sway me. On this, it has nothing to do with the profession of therapist particularly- I would feel that way about anyone I didn't know and didn't know the family/friends of. I was always interested to see how much people tried to control from the grave in their wills and funeral requests.
