I think you're right, and that this is an unfortunate omission.

The fix is simple though; we would have to add the leaf-list features
to import-only.  Probably refactor the "feature" leaf-list into a
grouping so it works like the grouping location-leaf-list:

  grouping feature-leaf-list {
    leaf-list feature {
      type yang:yang-identifier;
      description
        "List of all YANG feature names from this module that are
         supported by the server, regardless whether they are defined
         in the module or any included submodule.";
    }
  }

And then "uses feature-leaf-list":

OLD:

  grouping module-implementation-parameters {
    description
      "Parameters for describing the implementation of a module.";

    leaf-list feature {
      type yang:yang-identifier;
      description
        "List of all YANG feature names from this module that are
         supported by the server, regardless whether they are defined
         in the module or any included submodule.";
    }

NEW:

  grouping module-implementation-parameters {
    description
      "Parameters for describing the implementation of a module.";

    uses feature-leaf-list;


And in the list "import-only":

OLD:

      uses location-leaf-list;

      uses feature-leaf-list;
