I assume that OP is incorrectly describing zsh's default behavior
of intercepting risky ''rm'' commands and interactively requesting
confirmation.

    $ zsh -f
    % rm -rf /*/*
    zsh: sure you want to delete all the files in /* [yn]?

This behavior is specific to ''rm'' and can be disabled [*].  In
other contexts, zsh expands ''/*/*'' more or less as usual.  This
can be verified trivially.

    $ zsh -fc 'print -rC1 -- /*/*'
