`=platform` is used for production. Ie extraction.

Please pay attention it has already been added node/5787083212

Or the area should be on water for berthing. Not what it is berthed to.

`=visitor_berth` is used for a berth for visitors in facilities eg marinas. It's not standalone.

It's not not allowed, but something other than `=slipway` should be used. Please research before deleting others' work.

Please read carefully before you use tags randomly. `=berth` is used for individual berths, where there can be many at piers or quays. It is a point feature.

Please pay attention this is overridden by `motor_vehicle=no` + `bus=`

1. Please see the `=pedestrian` has `motor_vehicle=yes` already. The `highway=` class reflects the functionality.
2. `=track` should not be used for "single-track" roads. It's not physical, but functional for "wild" land access roads.

0. Please use more descriptive comments, and upload them in different changesets
1. Please don't blindly accept any editing software suggestions. That's lying to validators. You should at least read the "warning", which tells you Mei Foo Roundabout should be split. `layer=1` at the same time conflicts with many bridges along.
2. Why are you changing `=viaduct` to `=yes` as well?

Please don't draw a separate line for cul-de-sac without raised islands. It's considered a `=turning_circle` point.

Please don't use `=apron` for what's not an entire apron, or draw arbitrary areas. This duplicates the `=parking_position` line.

Please don't add descriptor labels to `name=` , which is for proper names only. This is not a printed paper map. They are harmful to a geographical database. `=aquaculture=` etc already expresses this.

`level=` should not be changed to `layer=` inside `building=`

In this case, it would be more straightforward to argue it's not `covered=yes` from how narrow and curved it is. But other cases, some users may find splitting `footway=sidewalk` to add `covered=yes` easier than drawing the entire `man_made=bridge` , then you have to ask why should the roadways not get `covered=yes` together.

In Germany, someone used 1 `covered:by=bridge`

It depends on what you mean by that. Certainly drawing a `building=` doesn't prevent `covered=yes` from being added.
The issue is there's no differentiation on when you should do that, and for long or wide bridges. Walkways can be specifically designed under viaducts to be sheltered. Then you have an arbitrary distinction on why roadways shouldn't get it.

Why did you delete a sidewalk section?

These don't show the exact reason, but it's critical for `*:lanes=` when `destination:ref:lanes=` and `destination:lanes=` have freeform text in `ref=` and basically `name=` . Using `none` would be interpreted literally as a `ref=none` or `name=none` there, so 0-length must be used.
