Seems pretty lame, at least on the surface.

Since JOB C/I and execution are not guaranteed to happen on the same 
system in a MAS, if the value for a given symbol is different on each, when do 
you want to resolve the symbol?  Some will say "at C/I", others will say "at 
execution".  Since the entire z/OS user community will not likely ever agree, 
IBM cannot unilaterally implement a resolution.  Either way will cause a large 
share of customers significant grief.

For STCs, C/I and execution happen on the same system (in JES2 at least), so 
you can safely use system symbols in STC JCL, as many of us do, extensively.
