Comment 10 for bug 898845

That section of the documentation has to do with the *library* being designed for embedded use, not the *upstream source* designing around embedding a library. It's referring to libraries such as some elements of the GNU toolchain, which are specifically intended to be embedded.

This is a case where Debian (and, by inheritance, Ubuntu) has made a deliberate choice to override the wishes of upstream. The fact that we have multiple Ubuntu releases with unsafe embedded libraries is just proof that embedding libraries is a bad idea.
