Yes, I know perfectly well. As you wrote: either ... or, but not both
of it. I'm wondering how you fix a road tagged with sidewalk=* plus a
separate parallel sidewalk without deleting anything?

They display all the sidewalks only on the plot map (Parzellenplan),
not on the city map. On the latter, the sidewalk is only mapped if
there is a barrier between the road and the sidewalk (which
corresponds to the recommendation on our wiki).

If this is general opinion, it would be best to add this information
to the [local tagging

That's only true for the standard layer, but the sidewalks can be
displayed too, like on this [ITO
map](http://product.itoworld.com/map/126). An option displaying them
could be added to the main page.

The question is: are OSM (or Maps.me etc.) users interested in seeing
this information by default or don't they find it distracting (because
it makes the map look cluttered)?

> Sidewalks have sometimes different surface than the street...

This can be handled with sidewalk:*:surface=*. It is even possible to
add width and kerb information.
