z/OS DISP=(OLD,DELETE) works without any problem to delete a VSAM cluster that you own. I use that JCL all the time to delete test VSAM files.
Creating a VSAM cluster may often require IDCAMS DEFINE, but the JCL LIKE parameter is your friend if for instance you are making a copy of a production file for a unit test run. Just use the UNIT and SPACE parameters to allocate space and all else will be copied from the LIKE cluster. Now if any of the LIKE cluster parameters are incompatible with your immediate need (REUSE vs NOREUSE perhaps, or LOG parameters for RLS) then you do need DEFINE, but the JCL DELETE works without an issue that I am aware of.

As far as I know,a VSAM file has to be explicitly DELETE/DEFINED using IDCAMS. -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
