Please check they are already `bicycle=use_sidepath` .

It is not needed to simplify anything in most cases.

Please don't merge or delete! They have different attributes.

Please don't add non-opened features directly. And `=attraction` is redundant Tagging For Renderer.

`=secondary` should be used for important roads across a district. This is not. It also needs to be consistent with On Kin Rd.

Please take care not to remove `building=` when adding `man_made=pumping_station` . They are different aspects. Also the latter doesn't render.

Please don't remove the address. It needs to be transferred.

`building=apartments` is an apartment building. However `residential=apartments` is an apartment complex that's basically defined for multi-building housing estates.

It is obviously meant for `landuse=residential` + `residential=` ....

Why changing `=apartments` to `=residential` ?

Please don't draw vehicle path curves. This is unrealistic, and needless complication. Follow the kerb line only.

Please don't use `residential=apartments` for single buildings. It's defined for housing estates.

Please don't use `=construction`. The road is built, and not destroyed.

2. Please don't add `wiki*=` to multiple objects. It should be unique.

Please don't add `shop=mall` to individual buildings of a mall. This is duplicating.

I'm not "telling you what to do". It's a notification that you can ignore if you wish. Don't complain when I change it back that is.

Please don't add descriptor labels to `name=` . It is for proper names only. Use `description:en=` + `description:zh=` .

`bridge=covered` could be used. It means fully enclosed. The namesake type can be indicated with `bridge:material=wood` . Eg `=viaduct` doesn't have to be steel or concrete. As long as it has many spans.
`covered=yes` doesn't have this meaning. It's not very `indoor=yes` either.

Yes there is. `substance=` is widely used and supported. Using `pumping_station=` prevents it from being used for other purposes.
You are the one changing it meaninglessly. I'm telling you why not to. There's no "rules". Doing something "wrong" is not the only reason for receiving comments.
Wiki is not for personal opinions either.
And you haven't considered `pipeline=substation`.
