Issue 26 -- "Relationships between labels" -- would be impacted
by such a decision [1,2].  Maybe we could go back to a suggestion
Guus made in March [3] as an alternative to Proposal Three
("SimpleExtension") [4]:

    I had an amendment of this third proposal in mind.
    Instead of having two properties skos:prefTerm and
    skos:prefLabel, I would suggest to have just the
    current one, skos:prefLabel, and removing the
    range restriction (rdfs:literal). So, this means
    that if one queries for the the skos:prefLabel of
    a concept, one either gets a literal or a resource
    with a label equal to this literal. This prevents
    the use of construction rules and keeps the SKOS
    vocabulary simple. The only extension to the
    current SKOS vocabulary would a a class skos:Term.
