     * The profile activation is done twice: once on the file model (so the model
     * which has just been read from the file) and once while computing the effective
     * model (so the model which will be used to build the project). We do need
     * those two activations to be consistent, so we need to restrict access to
     * properties that cannot change between file and effective model.
