It does do this.
Take a look at package.el.

Tassilo>   (package "my-package"
Tassilo>     (version "0.8")
Tassilo>     (need ">=emacs-22.1" "<emacs-23"))

I didn't implement "<" dependencies.
I didn't think this was worth the effort.

I didn't do this, either.  I think few people bounce between Emacs
versions this way.

Yes.  Assuming package A is backward compatible.  package.el doesn't
check this, it has no way to.
