Subject: Builtins like "exec" redirection are not printed with xtrace

It seems that the following produces no output
#!/bin/zsh
setopt xtrace
exec 1>/dev/null
Is there a reason that xtrace does not show the exec line?
Similarly, other commands with I/O redirection seem to not be logged in
xtrace, e.g.
$ cat xt
#!/bin/zsh
setopt xtrace
head -c 8 /bin/sh | xxd > /dev/null
$ zsh xt
+xt:3> head -c 8 /bin/sh
+xt:3> xxd
Is there a way to get xtrace (or another option) to log the I/O redirection?
