Just to note that the most recent release of Policy sort-of defines
ownership of this, though it is not as explicit as the TC decision:

    Packages must not install files to paths whose first component is a
    name directly under the file system root and which is a symbolic
    link to a directory of the same name under "/usr".  ...  The
    base-files package is an exception, for it installs aliasing
    symbolic links from "/bin" to "/usr/bin", "/lib" to "/usr/lib", et
    cetera.
