Is it useful, or even safe, to define SMPPTS* in other than GLOBAL zone?

Does SMP/E warn or prohibit inconsistent SMPPTS* definitions among
zones?

(I remember Ed Gould claimed it was safer to supply DD in JCL than
in DDDEFs.)

In the Ref.  I read:
    It is recommended that SMPPTS be allocated as a PDSE (DSNTYPE=LIBRARY).

    If you plan to run concurrent jobs, specify DISP=SHR instead of DISP=OLD.

Does concurrent, DISP=SHR, DSNTYPE=PDS work?  How does SMP/E serialize?
Like ISPF member serialization?  Other (specify)?
