Of course TSO is optional in the plain meaning of the word, beyond de minimis use at least. That should have been clear from my Cognos example. To pick a couple more random examples, z/OS Version 2 includes the z/OS Font Collection and the IBM Directory Server for z/OS. Must you use those elements? I hope you do, but no, their use is optional. They are shipped at no additional charge with the base operating system, and surely that's a good thing, but so what? When I use Cognos, I'm a z/OS user. I'm not a TSO user. There are literally billions of z/OS users who are not TSO users. As another analogy, there are also billions of Linux users. All Android smartphone users are Linux users, for example. Only a tiny fraction of Linux users are bash (the specific command line shell) users. A bash restriction would only be meaningful, if it's meaningful, to bash users specifically. Not to all Linux or all Android users. And that simple, factual observation doesn't change whether bash is or is not sitting on the disk (or flash memory) of the particular Linux device. ....But, don't get me wrong, I'm certainly not opposed to longer length TSO user IDs! I wrote that I'm in favor. I recommend letting IBM know what business problem you're not solving today that you could be solving if TSO had longer length IDs. However, if there's no "tree falling in the woods," then what are we worried about? A "restriction" matters only if it, er, restricts. Please tell IBM what actually restricts you from solving a business problem, or at least could based on reasonable forecasts.
