Hoi,
When you look at the current use of labels, they are used to identify items. When a statement is used on an item, it uses a combination of a property and another item. What we notice is that several not so smart choices have been made in the past that make the current use of labels problematic. I remind you of the discussion of calling an item a list when it is used an a single instance.
The notion that labels on statements are not used flies in the face of it being applied in Reasonator for instance.
Forget about what a structured Wiktionary will do in abstraction, it is not where we are. We are at a point where we have labels and no clue (in a Wikidata context) if and what practical benefits embedding Wiktionary will bring. It is really nice to point to "Lemon" and say that it is a standard. But as far as I am concerned it is a lemon [1] when there is no translation in how the information can be leveraged.
I can appreciate that we have simple labels at this time. It will not stay that way. The alternative is that including Wiktionary in Wikidata will truly become a lemon [1]. I will do what I can to help prevent that, my ambition is that Wikidata will truly replace Omegawiki.
