Um...? If the trigger voltage was much too high, and the camera did not
have overvoltage protection of some sort, your problem would not have
been flakey flash operation, but rather burned out shutter electronics.
I suspect it was a polarity problem. Some of the voltage isolation
electronics are polarity sensitive, older mechanical sync were not. You
most likely could have fixed the problem by switching the sync leads in
the hotfoot of the flash.

Since then I've been careful not to mount high voltage flashes on
newer camera bodies, (I've since sold the ZX-M). I haven't used the
Vivitar on anything other than older mechanical bodys since.

Possibly invented by lawyers with liability concerns.
No, I think there were some cameras made with limited hotshoe
ratings. Perhaps those were Canon or some other brand? Apparently,
many people assumed that all the new cameras had this limitation.
It's also a good way for camera store sales people to sell you
completely new flash equipment, when you might not really need it. I
suspect that some shops intentionally don't want to know which
cameras are safe with higher voltages, because they want to sell more
of their new lower-trigger-voltage flash units. I know that my local
Pentax dealer claimed the *istDS needed a low trigger voltage.
In fact, the first person I reached at Pentax didn't know the answer,
but even he seemed to think that perhaps the *istDS might need a low
trigger voltage. It was only when he transferred me to Mark (a higher
level of support), that I got an accurate description of the truth.
take care,
