I look at AE vs. GPON differences being electronics and heat. Strands are cheap and not worth worrying about to me.

Doesn't that almost entirely negate the cost advantages of GPON, namely, that there's a lot lower strand count and your fiber outside plant design can use passive prism splits for the transport to the actively AC powered network node? You realize the transport core to the gpon OLT chassis is still active fiber in many designs, right?

I also am unsure if you are aware of the upgrade process to NG-PON2 - you can run it on the same fiber strand as your existing PON split. Add the new card into the chassis and move the split over to the new SFP. Upgrade the customers at your leisure.

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.

The size of your backbone ends up being monstrous with active, as well as having to keep the cabinets powered, UPS+batteries, enclosurers maintained, etc. PON is simply so much cheaper are scale, and in residential every dollar counts.
