Isn't it possible that the subsystem name occurs elsewhere and/or has been
in some way added to a hashed lookup scheme this would break?

And this hash scheme isn't a documented interface so it's don't touch
or even look at.

looking at SSCVT mapping:
https://www.ibm.com/docs/en/zos/2.5.0?topic=xtl-sscvt-information

24      (18)    ADDRESS 4        SSCTSYN        HASH TABLE SYNONYM POINTER 

So there might be some sort of hash table indexing these allowing
z/OS services to avoid a linear search down the SSCT chain.

I think that the SSCT is a creation only item, no delete, and now should only
be created via the z/OS services designed to create it.
