The biggest issue I see with doing this (for residential users) is the fiber handoff. For 25Gbit, the very minimum is going to be a SFP28 module with an LC connector. The linked Init7 article is a bit light on details, but consumer grade hardware is not even close to that that in 2022. (SFP Ports OR the packet processing power to move that much traffic!)
Maybe the OTO Init7 installs on the house breaks it out into multiple 1Gbit or 10Gbit links to be more compatible? Even then, in the USA, basic SFP+ 10Gbit fiber, (inside the house) is rare in a residential setting. (Most fiber-based ISPs in the USA provide a 1Gbit copper uplink inside the house.)
