One other thought about all this: in the past, one objection that's been raised to deleting files during crash restart is the possible loss of forensic evidence. It might be a good idea to provide some fairly simple way for developers to disable that deletion subroutine. I'm not sure that it rises to the level of needing a GUC, though.
