Please check guidelines and the status quo. Only Tunnel Area will be `=motorway`

No it does not! It is not public.

Although it is Exit 2, it should be treated as `=motorway` main line. Otherwise, the main tunnel has to be `=motorway_link` as well.

Tunnel Area is at the eastern end of the interchange. It is possible have `noref=yes` `=motorway`.

No, please don't mark them as open until at least that day. This doesn't make sense for daily updates eg OSMAnd Live. For new developments, applications should be tracking as change. Another option is user setting constructed roads in routing.

No you should not use `=route_marker` when it is not such. This called lying to the map to make it show up. It can't show everything for everyone.
Eg https://gk.historic.place/historische_objekte/l/en/index.html#Anfang will show `man_made=survey_point` + `historic=yes`.

Please use `description=` for labels.

You need to completely transfer all info if you even want to delete something.

@Austrianton This won't do anything to Organic Maps / Maps.me uploaders. Better follow up on their Git issues to limit changeset extent.

OSM is about existing concepts in the most common use by the public. Use OpenHistoricalMap to reflect origins and evolutions.

Please don't mix up different levels.

Please don't attach unrelated features to other unrelated features especially roads. This doesn't represent reality, and makes editing difficult.

4. Use OpenHistoricalMap to record the full history

3. Descriptive changeset comments please

1. Please don't remove other names. Move them to `alt_name=` etc.
2. `name=` is for the most common name in use by the public only.

Please don't change `escalator=yes` to `highway=steps` + `conveying=yes` on features. It is used to mean whether it has escalator, not that it is an escalator.

Please don't add useless `name=` to carparks. This is misleading.

`highway=corridor` + `indoor=yes` is not valid. It is mixing archaic and the existing standard. Use `=footway` + `indoor=yes`. `layer=` should not be used either.

This is already included in `tunnel:name=`. It is not a major tunnel that qualifies as commonly known in `name=`. Similar to Airport Tn on Tung Wing Rd.
