This is the beauty of TPS: That they're not afraid to get into some advanced features that may take time (more or less depending on the user's background) to learn. I know that when I load up TPS for the first time, I will not be able to instantly throw together a working flat ride, but it will be exciting to learn and explore the features provided. Think about it: An interface to create your very own flat ride, that you can quite possibly experience a POV of (hasn't been confirmed yet if you actually can). Either way, this is completely unprecedented; never been done before.
Perhaps one of the strengths of part of the RCT3 community is how open people are to share and reuse things; a huge contrast to NoLimits were few things are ever reused and require clear permission from the creator to use. From what it looks, TPS's community may have the same advantage, which, even if you prefer to make your own stuff exclusively, is still nice to have. (i.e. Why model your own Carousel when someone on the exchange or community repository has done a much better job already?) Something like a "Sketchup Warehouse" could be a great idea for TPS.
