no, you don't have to, you can also use both tags if you think they should
apply both.

having few keys and many values has a certain advantage in certain database
systems, turning this the other way round will not let you gain much but
will have negative implications for those systems. Plus you loose the
generic "classes" that might be useful for finding tags or for filtering
(e.g. "all shops in this area" is harder or impossible if the scheme goes:
grocery=yes / shop).


And what about presets? Will there be two of them?



If we want to have consistent tagging and details, simple "presets" the way
we have them now will not be sufficient. We should better have a guided
scenario (aka "wizard") that asks the mapper some questions and in the end
proposes the tags to set or states that there aren't yet tags for this kind
of thing. This would also decourage people from using similar but not
pertinent tags.
