Croaker hopped off?

One thing I would like to mention. We have heard of two unspeakables 
in OotP, Rookwood and Bode. Both of whom had significance for the 
plot, or Voldy in one way or another. In GoF Croaker is also 
mentioned to be an unspeakable, at the QWC. Now we all know very 
well that JKR does not waste words. Why has she mentioned him, and 
not give him any screenplay? Or might he just be important for 
future books? It would seem highly unlikely that he does not come 
into play at all anymore. 

Thought?
