What might be an issue is the lack of experience with "fallback options", e.g. pilots not being used to fly conventional navigation SIDs without FMS guidance any more. That needs to be trained and pilots should be allowed and encouraged to reduce the level of automation used during normal operation to stay sharp. Company policies or individual captains prohibiting this are counterproductive.
There was a gentle reminder from management the other day to say that if you are planning a raw data approach, please be mindful of the conditions and brief how you might fix it if it goes wrong. It also reminded us that other operators have recently banned flight without AP/FD unless on the last section of a non-precision approach.
I do tend to very briefly discuss a navigation headache at take-off, but only to the extent of "if all the clever stuff falls over shall we ask for radar vectors?".
