in the general thought that most aircraft will climb out clean with the best rate tommourie is basicly right, but thats all.
a jet driven corporate or airliner will ususally climb through 400 feet that quick you will hardly have time to think about raising flaps below since you just verified gear is up while your colleague calls first time radar frequency.
when between this and acc altitude an engine fails it should have nevertheless enough juice to climb and meet obstacle clearance . and you have in this case other things to do than change configuration.
and finally... the guy who truly tries to feed his family sitting infront really has other thoughts than debating day after day when to raise flaps exactly and why. this discussion dear gents is like most discussions on this forum a pure theoretical chair view.
@ empty cruise : innsbruck 26 is initially visual departure only. check your pdf charts.
