+# TODO:
+#
+#  - Refactor using `bash-completion` "library" but keep backward compatibility,
+#    as this would otherwise break the "no more than 3 dependencies" approach to client-side `dfi`.
+#
+#  - When possible, add completion to existing `dfi` arguments that aren't completing
+#    * e.g., `dfi archlinux/${USER}:default edit type=` -> `dfi archlinux/${USER}:default edit type=rules...`
+#
+#  The not-so-straightforward resolution to this TODO hinges on the fact that
+#  the default delim for all `dfi` completion is the `=` character (which also exists in `COMP_WORDBREAKS`).
