i makes a lot of sense, just think of

    Kaufleute = Kauf ++ leute (merchant / trader, from kaufen = to buy)
    Kaufläche = Kau ++ fläche (chewing surface / morsal surface from kauen = to chew)

But I am sure only professional typographers + a small minority of pedants (in the good sense) would be aware of this.
