Yeah, from a cost/redundancy/etc perspective it rarely would make sense to run 1.

I will get pre-terminated for MTP runs, but not for anything else. Fusion splicing connectors just isn't slow (and if i need to go quick, i'll just splice a pigtail onto it until it fails)

I agree for redundancy, etc, better to just add more until loss-of-ROI occurs, but will say doing something for extra capacity for home users/even business users feels like massive overkill these days.

Even 2km 100G duplex transceivers for SMF are <$200 a piece now. Cost is dropping crazily fast. (bidi simplex ones now also exist on fs.com as of a month or two ago, but are still way too expensive)
