Preferred way to map landuse=residential? (lemmy.world)

I've encountered some conflicting usages of Tag:landuse=residential. Some areas are very specific, and broken down into individual blocks, while some areas cover multiple blocks. Here's an example of both styles adjacent to each other:

https://www.openstreetmap.org/way/652122607

The wiki doesn't really say much on the topic. Does anyone have opinions/rules of thumb on how to tag them exactly? It seems like all adjacent areas not separated by major highways should be joined together?

I've encountered some residential areas that are broken down into mapping each block, and literally follow the curb, rounded corners and all. That seems too specific?

@BitSound @openstreetmap
There is no real reason to break things up block by block unless the blocks have unique names or something. It's also a pain to edit when the areas have been glued to the roads.

So yeah, leave them big.

Makes sense, thanks!

I do both depending on level of detail in general. If every tree and trash can is marked and the roads have odd geometries, then clearly defining a residential area to be inside a block works best imho. But if there's a big area without many other features I just map it as a big residential area until more detail is added. Area nodes should never share nodes with road nodes though.
