Key part there is, *is going to be*... is it available or shipping now? If somebody wants to start a build now, the choice is between GPON or active.
Having an active fiber path, even with just one strand (for BiDi optics) gives you a nearly infinite lifespan of the installed light path and cable plant, if things are maintained correctly. With a dedicated light path from each powered network node to the customer you could upgrade to active-E 10, then 40, then 100Gbps someday. Yes we will see customers with 10GbE optics in the next ten years. And maybe in 20 or 30 years from now it'll be cheap and easy to connect each customer with an SFP-sized coherent QPSK 100GbE optic at each end.
