display better the categories in url ?

So.
If I make those categories :
/food
/food/chinese
/food/italian

The url shows like this: /listing/food or /listing/chinese

I don’t like the /listing/ but I don’t mind it, if we can modify it so it shows instead, the categories in a normal hierarchy? Like this:

/listing/food/
/listing/food/chinese
/listing/food/italian…

I wonder why this hasn’t been done yet. WordPress already does it. The categories are taxonomies, so what’s stopping from having the urls like this?
