I don't think performance is the issue any more -- but RACF, for example, has CONTIG coded in the sample JCL member RACJCL because the RACF database must be allocated in one extent.

There are a few other places where this is true. For example, the JES2 checkpoint and SPOOL data sets must be CONTIG.
