I suspect that using the STEPLIB or JOBLIB mutually exclusively within one step was influenced heavily by the cost of "core" way back when the TCB and the initiator were being designed, maximum machine memory sizes were MUCH smaller than today, CPU cycle time was much longer, etc. Many other design decisions were forced by those constraints, also.

If you REALLY want to fall back to JOBLIB if you do not find the module in STEPLIB, you can just add the libraries that are in JOBLIB but not in STEPLIB to the end of the STEPLIB concatenation. Changing the search order to not fall-back from STEPLIB to JOBLIB at this time is not IMO viable (even if this was made optional via a PARMLIB setting).
