That is not correct. The WAT limits are a certificate limitation and apply regardless of obstacle clearance considerations for all types of operations.
It is correct, as long as you are within WAT limits and there are no obstacles to consider you are not climb limited! Or are you suggesting that it is allowable to takeoff outside WAT limits?

Obstacle clearance by the Net TOFP is required by operating regulations such as FAR 121 for Air Carriers.
Which is what I said, as long as the gross flightpath minus 0.8% (=net flightpath) clears all obstacles by 35ft. If it doesn't you will be restricted by a 2nd segment climb (since we are discussing the 2,4% requirement) limited weight. Thus you will be climb limited.
