   + Remove `map_to_list_empty_inv_alt`; chain `Permutation_nil_r` and
     `map_to_list_empty_iff` instead.
   + Add lemma `map_filter_empty_iff`.
+- Add generalized lemma `map_filter_insert` that covers both the True and False
+  case. Rename old `map_filter_insert` → `map_filter_insert_True` and
+  `map_filter_insert_not_delete` → `map_filter_insert_False`.
++ Weaken premise of `map_filter_delete_not` to make it consistent with
+  `map_filter_insert_not'`.
 
 The following `sed` script should perform most of the renaming
 (on macOS, replace `sed` by `gsed`, installed via e.g. `brew install gnu-sed`).
