It often is. But consider the plane as well. If the plane has a low stall speed, then it won't matter much - true it won't really accelerate until it's built a bit of speed up, but it's not a problem.
The really awkward combination is a high stall speed and a prop that is ineffective at low speeds. It's either very hard to build up speed (ROG) or you need a very
good throwing arm.
