By the way, destructuring-bind supports full Common Lisp style
argument lists.
I don't mind having some of this in that special construct, but I am
not sure we should document all of the features.

Just curious: Why not?
It is added complexity that we don't need. To add them to standard
Emacs Lisp functions would call for documenting them with great
importance. To have the alternative constructs `function*' and
`defun*' is kludgy.
It is one thing to have `function*' and `defun*' in a compatibility
package. It is quite another to give them legitimacy in Emacs Lisp.
For example, typing ?C-h a union RET? in my running Emacs reveals
union (from cl), gnus-union and gnus-sorted-union, ediff-union, and
jbw-sorted-number-list-union (my own). And I wouldn't be surprised to
find other packages (which I haven't loaded in this Emacs) that also
implement union.
The fact that Gnus and ediff want a union function is not enough
reason to add one as an Emacs feature. In fact, there are four
packages in Emacs that define a union function. I don't think that is
enough to justify adding one _and documenting it_. It would take
considerably more reason.
(callf2 delete macro (cadr p))
(callf2 concat "[" (car return-value) "]")
I find callf and callf2 extremely counterintuitive, and I would rather
people write that code with setf.
