It's up to the operator. The manufacturers don't concern themselves with obstacle clearance, per se, or with the manner in which the takeoff path is flown. The manufacturers assure the aircraft with meet the Part 25 takeoff flight path at MTOW under optimum conditions, and provides OEI data for various weights, elevations, temperatures and runway lengths.
The operator then has to assure compliance with 121.189, or its equivalent. Many today now use the Part 25 takeoff path applied to AC 120-91, rather than the impossibly narrow lateral limits specified in 121.189.

Large operators have their own planning and performance departments. Smaller operators often use contract planning and performance companies.
