On what are you basing this assertion?

I don't agree.  The documentation barely says anything about any
of the behaviors you modified, and zsh is not a POSIX-compatible
shell, so it's entirely reasonable for users to have accepted the
previous behavior as intentional.

This is only incidentally true.  The documentation omits many details
about ERR_EXIT's special cases, so your changes largely fall between
the lines (so to speak).
