shop=hardware seems to be about let’s say, nonanimated devices? So rather nails and screws and hammers?
And yes, this kind of shops seems going extinct, at least in my area
While shop=doityourself seems to be more of supermakety: you can get there power tools and nails and planks and lightbulbs and paint and tiles and bathtubs and plant pots and soil and mirrors and not entirely dead plants.
As the next step I plan to (when I have both hobby time and access to a real computer) implement a PR adding it. (if anyone is interested - feel free to make one yourself, I may end doing it in 2027)
