How do I disable form autosubmit?

People have been begging for this at least going back to May, and in the intervening time, people have posted a number of examples of it causing real problems and have posted at length how this is, in fact, a security bug. Heck, in July, I posted about how this directly led to leaking a bunch of my own family's PII and private information to outsiders. These are serious security concerns.

The bottom line is that this "feature" is a disaster, as you guys knew it was when you killed it the first time around in the v7 days. Yet, a fix is still only on the roadmap? That suggests some time in the future other than the near-future, and it's already been months and many releases. I'm pretty patient, but this is not the type of fix that should take months or (gulp) years to implement. If adding a toggle in the UI is that complicated, then just delete the one or two method calls that trigger the submit; it's better we have to wait for the toggle to get the feature back than wait for the toggle to be able to disable the thing.
