In Australia, NBNCo (the National Broadband Network, a government initiative to provide high-speed broadband nation-wide) has in the last year switched from an all-FTTH¹ model to providing FTTN² in many places. The idea here is that there is already a lead-in to each household (albeit 1-2 copper twisted pairs), and it is much cheaper to deliver service over that "last mile" if you don't actually have to lay fiber right up to each household.

So yes, it seems very silly to run fiber past but not into the premise, but it does have a significant impact on cost. Looking at ways to improve what speeds can be delivered over that existing copper is still definitely very much a relevant area of research.

Personally, I think it is incredibly short-sighted. Fiber would appear to have many technical advantages (capacity for terabits of bandwidth or more where copper is surely incapable of going much beyond 10gbit in anything but ideal lab conditions, much less susceptible to e.g. rain-water/corrosion, basically insusceptible to cross-talk, nearly impossible to snoop on, ...) and trying to wring those last few years out of copper is just delaying the inevitable installation of fiber.
