...it may assist ATS officers in understanding why we make certain clearance or other requests, for example, asking for non-standard routes over rough terrain or large bodies of water, particularly when IFR flights may be expected to plan via standard published routes, which are not necessarily conducive to flight safety in the event of engine failure, or where weather and/or turbulence indicates safer routes are available.
I would have thought anyone asking for special clearances or requests for the above reasons would have received some understanding.
