docs: Returns true if the specified word shaper doesn't use
  known lower case words, even if a list of them is present.
  This is used for backwards compatibility. It is suggested that
  new word shape functions are either passed a non-null list of
  lowercase words or not, depending on whether you want knownLC marking
  (if it is available in a shaper).  This is how chris4 works.
  
  @param shape One of the defined shape constants
  @return true if the specified word shaper uses
  known lower case words.
