cl-extra.el : any support for bool-vector type?

Was surprised to see that

    (cl-map 'vector #'not '(nil nil 2 3 nil 5 nil 7 nil nil nil 11))

is accepted by emacs while

    (cl-map 'bool-vector #'not '(nil nil 2 3 nil 5 nil 7 nil nil nil 11))

fails with (error "Unknown type bool-vector").

Turns out that cl-extra.el does not support bool-vectors. Is there any
reason for this? Not knowing of any, I've just added one line to
cl-coerce and now I can coerce to bool-vectors. See attachment. Let me
know if I'm being reckless ...  -phs
