One of the reasons to do it implicitly is placement, not that it really matters, but if you want it next to the VTOC you may want to do it implicitly.

Even though the storage team implicitly defines a VVDS at the shop I spend time it (usually?), we had this command in place prior to z/OS 1.13: F CATALOG,VVDSSPACE(30,15) So 3x larger for primary than the default TRK(10,10). Now we have it in IGGCATxx since z/OS 1.13 as mentioned.
