I believe zsh is being faithful to the "rc" shell's behavior here.  The
doc note about "historical reasons" was added pretty recently, as was
the override of that behavor that's possible by using @s, so it's most
likely that there was always and intentionally this exception but that
it was missed when the doc was updated.
