I expect this to become more common in cities in the Netherlands for existing neighbourhoods built between the 1920s and 1970s. These older houses (of which there are a lot) are difficult, if not economically infeasible, to convert to heat pump heated houses. Insulation can be done to some extent — I've managed to insulate my 1930s house to a thermal resistance of R⒞ = 4,5 m²K/W in the attic and parts of the level above the ground storey, but this is not realistic for the ground floor — but it is not feasible to reach the R⒞ ≥ 6 m²K/W mandated for newly built houses. The noise is a serious problem too. In terrace housing you simply can't expect everyone to install these things and maintain a sane level of quiet. Better to solve this problem by insulating as much as possible, and to provide heat by collective solutions such as geothermal heat on a neighbourhood scale. The current 'let-the-citizens-solve-this-themselves' approach of our government is making homeowners insecure about what to do though.
