There are often 'engine-out' performance considerations past the end of the calculated performance altitude (often only 1500' AGL), an example being taking off from Bergamo and heading north. An engine failure later in the climb requires 'action' to avoid flying into those big lumps by ensuring MSA is achieved (if not returning south). These issues are rarely 'calculated' into departure tables or included in airline airfield 'briefs', should be 'common sense' ('airmanship? - acknowledgements to 'Ag Bis') and it is a good idea to bear them in mind when accepting 'direct' short cuts on departures unless visual all the way.
