Just because you can get a 25gbps residential line doesn't mean there are lots of licit use cases. You would need someone at the other end to open a big enough pipe to you for it to be meaningful, and most content providers etc aren't going to allocate that much bandwidth to a single user.
Inside the home, as others have said, there are really no multi-user use cases that need or can even make use of that sort of bandwidth and for the rare single use case that exists (basically, uncompressed RAW video editing) as others have said, you'd be better off with DAS. And that doesn't look like it's going to change any time soon, codecs and compute are improving faster than consumer demands for video quality (already very much into diminishing returns).
The oddball stuff like the XikeStore switch is either chasing a niche within a niche within a niche (only feasible with the AliExpress market reach) or it is intended for what I'd kindly refer to as the DIY commercial data center market, and not 1st world residential.
My personal take is the modern home user would be much better off with WiFi advances to actually catch up to 2.5gBE / whatever their internet access is, than a significantly faster, significantly more cost and power-intensive LAN they have no meaningful means of getting data onto, off of, or across.
