In my type we brief to climb to acceleration altitude (400 feet AGL) with a windmilling prop (NTSing), T/O flap and gear retracted.
The only time we will feather the engine straight away is if we have an NTS failure in which it will happen as soon as the gear has been selected up.
A turbine engined aeroplane above 5700kg is certified to achieve a positive rate until the gear has been selected up, then must achieve a certain climb gradient until the end of the second segment, which in my case is 2%. This is with a windmilling prop, gear selected up and take off flap extended.
We do this all the time in the sim, and on our base checks and it performs well. In the sim at max weight it also performs above the minimum required climb gradient provided you maintain V2 with correct technique.
