I was mostly removing these without replacement, because IMO the upper comment is good enough for both index and name based scenarios:

- If a column in `columns` is not in the input table, a
  `Missing_Input_Columns` is raised

If a "column" is not in the input table IMO works both when the column is represented by name, selector or the integer index.

Here, an exception - the Text case has some specific explanation and behaves slightly differently here. So I keep the special case for 'index' because it differs from Text here. I just update the comment to tell the current state.

(this is due to handling differences caused by trying to parse the text as expression)

LGTM - a nice simplification.
