This was supposed to go to the list.

Bad example.
There a lot fewer people authorised to issue any operator command vs submitting 
jobs.

Also, no matter how IBM implements it, there will be complaints.

And, what happens if an ISV starts using it, and you now need parms set to 
something different to what you are using?

Here are a couple scenarios:

1. Pick execution system. The JCL has already been parsed and tokenised. How do 
you substitute?
2. Pick submitting system. The values controlling certain variables are 
different. How do you resolve?
3. Pick converting system. What happens if it runs where a variable is 
different?

What do you do? Keep an 'infinite' table of possible values and convert just in 
time.
That would be a re-architecting of submit, convert, execute to submit, 
determine executing system (the only one with true guarantees), then do 
conversion.
If I don't have SYSAFF, I don't know which system it will run on until it 
percolates to the top of the queue.
And, what happens if an initiator is no longer available after final conversion?

If you can not guarantee (repeatable) results, you should not implement/support 
it!
