well, this particular one is not impossible with ledger:

class View: UIView {
   part Feature1    // *** default
   optional part Feature2   // *** the behaviour you describing
}

class View: UIView {
   required part Feature1    // *** opt-in
   part Feature2   // *** optional, the behaviour you describing
}
