That depends on how you feel about Russian Roulette. I agree that "In most cases, that just isn't a problem. ", but that's not much comfort in the rare cases where it is a problem and you failed to check. Remember, even paranoids have real enemies. But it's not my dog.

This was despite having upgraded several other products over the previous year or so. There was a lengthy period starting in the 90s where we installed nearly every OS release, including those on six-month cycle. (Whew!) We habitually contacted ISVs and built recommended conditioning into the schedule. In the 2.3 upgrade, we miscommunicated with one ISV and overlooked the other. Bam and bam. You may get lucky, as when blowing through a full stop without a scratch, but I would not bet my reputation on luck. . .

Upgrading when it's not necessary can be counter-productive for some sites. While many vendor products do require some maintenance to "fully" function, especially those that interact directly with the OS, that doesn't mean that older versions won't work, and in fact, some "newer" products might no longer operate the way the site needs or wants. That doesn't mean that the OP should do something stupid, but they don't have to feel that they need to look at their task as if it's a huge project either. I respect your expertise, but when it comes to migrations, I have performed, and still perform several at a time from some pretty old releases to the current ones, and having just this past year upgraded 5 sites from z/OS 1.12 and several older releases to z/OS 2.3 (and in one case 2.2), I can tell you that while it's ALWAYS a good idea to apply AVAILABLE maintenance, there is no reason to worry that something will not work at all just because you don't have the latest copy/version. In most cases, that just isn't a problem. No one said that they should not upgrade as they go, but doing it all at the same time is not always the smartest thing to do.
