Inconsistent rendering of generic taggings in case of catch-alls (shop=yes, office=yes)

[imagico]

We currently have a number of catch-all renderings in the style were we depict features with a certain key independent of the value. That in particular

• building=*
• shop=*
• office=*

for building and office we do this for the value yes like for any other value while for shop we explicitly exclude shop=yes. In all three cases the yes is broadly accepted as valid tagging if a more specific classification is not available to the mapper.

IMO we should:

• treat shop=yes and office=yes equally in that regard.
• probably show both in a way that explicitly communicates incomplete mapping - to clearly communicate that while this is a valid value with a well defined and consistently used meaning it is not just another type of shop/office but indicates something semantically different - like highway=road for roads.

For building=yes i would not suggest a special treatment because it is so widely used without being broadly considered to be lacking more specific information.

See also #4723.

Above sounds reasonable.

182k shop=yes and 80k office=yes. In both cases about 70% have names.

Possible suggestions for rendering that would hint to both map user and mappers that data is incomplete:

1. Use a lighter shade of shop / office colour for dot and any name. Using a lightened colour rather than reduced opacity might cause less semantic confusion with private access e.g. on parking.

2. A common grey colour (as in highway=road) for "incomplete objects". This has been suggested, but probably too jarring.

Use a lighter shade of shop / office colour for dot and any name

We already use that for access restricted POIs so it would be confusing.

A common grey colour

We already use gray dots for bollards (small) and waterway barriers (large):
