When have we ever suggested that people *shouldn't* test their apps
before committing to a major version update?

I think the whole thing has been significantly overblown.  We have made
incompatible changes bigger than this one --- and, often, harder to find
let alone fix --- in almost every major release.  This one you can at
least be pretty sure that you will get an error, and not a silent change
in behavior, if you fall foul of it.
