That section of policy talks about _dependencies_ whereas the change 
done above is a _build-dependency_.

It is a common pattern in Debian to provide a virtual library 
development package.  Purpose of the section above is to ensure 
deterministic install (non-random install) but that is ensured by the 
maintainer of the library package only having a single package available 
in any suite at a time providing the virtual package.
