Agreed … whereas I did not give a recommendation but just described the “status quo”.
Although I tend to agree this is at least questionable. I have just been informed that using correct tags on an object to support rendering is not “tagging for the renderer”. That would only be the case if completely false tags are used to enforce a certain rendering, see this post:
From that point of view it would be fine to make a choice on how to tag a business based on the way how it would be rendered in carto as long as there is no conflict with a wideley accepted tagging rule for such an issue.
