For sure, those searches are more about showing what’s possible (and making browsing fun) than what a high-intent buyer would actually type in.

That said, from speaking to a lot of London buyers, people are often more flexible on location than you’d expect. The real criteria tend to look more like: “3-bed house under £700k, 30 min commute from [office], near a park, low crime, good schools” rather than “3-bed in Hackney.” Basically along the lines of the location / mapping data you're suggesting.

We’ve already built travel-time search and plan to layer in more of that other 'services' style data in the next few months.
