Display Warning when custom params conflict with global

On a multi lingual site I had some custom params set in my config like below. This seems to conflict with the global languages config setting. When I had this custom param set. The translated content would not build other than the index. No warnings where displayed with verbose output. Could Hugo display a warning when a custom param may conflict with a global or does like in this case?

    - Python
    - Ruby
    - Console

We could, but you would have to create a GH issue to track it.
