   That depends on whether one thinks the tests done to measure   
   quality are sufficient to determine all the axes of "good   
   properties".  I'm not inclined to think that they do.  The   
   set of tests done in the TestU01 suite are quite good IMO,   
   but I don't think they measure all the properties of interest.   
   I prefer to err on the side of caution.
