So Ferrari aren't going to appeal the decision for Vettel's penalty, but they are considering some kind of post-race review. The only thing is that a review requires some kind of new evidence to be present that can re-open the incident. I highly doubt Ferrari have that, so I personally predict that this will all fizzle out eventually.
The reason for that is because the regulations explicitly state that a time penalty cannot be appealed against - had Ferrari tried to directly appeal against that penalty, it would have been thrown out immediately as inadmissible.
Asking for a review seems to be Ferrari's way of trying to pressure the FIA into doing something, particularly since it seems that at least one of the stewards from Canada will be participating in the French GP. I do wonder, though, whether this is necessarily a sensible decision by Ferrari - they had a fair amount of public sympathy to begin with, but if they drag this out, only for it to then peter out if they're unable to provide any conclusive evidence, it is likely to start eroding support for their position.
