None of those need an upstream faster than 115 Mbps.
One 4K Bluray rip from Plex can do 60-80Mbit, Gigabit would allow an extended family to share the same library without the quality loss of streaming services and not having to be cautious of more than one person streaming at the same time. It might not be something most people care about today, but I'd certainly do it and I'm sure I could find others who would too.
With respect, I disagree ...... as would any business worth its salt.
You don't work your model on if's, but's and maybe's ... you work it to demands with a modicum of future-proofing thrown in.
Your scenario's may never, ever happen in the real world, or, it may be a very small percentage make use of a 1G symmetrical bandwidth. Fast forward 5-10yrs from now and demand may scale up from the customer, that is when you apply the future-proof hardware that was factored in originally.
You mistake my point, I didn't mean this from the network perspective - I meant from the end-user perspective which in turn will drive the network.
Like I said, I totally understand ORs viewpoint on rolling out GPON because its a much cheaper starting point and right now enough for 99% of customers. Then if demand for Gigabit starts to cause contention, they can roll out XGSPON on a PON by PON basis, that makes total sense on the scale OR are working on.
As an alt-net I can also understand how wanting to one-up the competition, and having a smaller rollout to OR, it might make sense to go straight to XGSPON. No doubt there are contractual reasons such as 5G towers along the path, etc, that may make it more financially viable. I can't see them doing this if there is no benefit to them. Even if that benefit is just marketing, its good for them to be able to claim "faster than BT" and potentially get contracts with ISPs that want to sell faster services exclusively through them. At the very least it could pull business contracts away from Openreach.
Personally I can't imagine getting 10Gbit as surely not going to be cheap, the cost of a router to push that would be insane unless I ditched pfSense. However I might consider 2Gbit, and I certainly would rather have symmetrical Gigabit than 900/115 as it opens up interesting options for hosting my websites by proxying the content off my LAN rather than paying for more VPS storage. Sure I could do that now, but its far more likely to impact my normal usage if I did.
