Maybe the services didn't exist yet when the original code was written?
Very likely.
What do you think of this, is it ok to do it this way? Are there any drawbacks? Do you have any hints in general? Would you consider to rewrite significant parts of these subsystems to use the (new?) services? I don't think that we have the resources to do so at the moment.
SSOB and SSIB contain subsystem names. A hash table is used to locate subsystem control blocks from the name. If a program manually adds subsystem control blocks to the end of the SSCT chain, hash table lookups for that subsystem will fail and require fall-back to sequential lookup resulting in longer path lengths.
