It depends on the use case.
E.g. DEC Ultrix did not have shared libraries, but it did have demand paging and sharing of binaries. On a typical multi-user system at that time, all users ran sh, vi, matlab, and mosaic, which thus could be shared.
On a modern single-user system, the user runs a few large applications, which cannot share much, unless they use the same shared libraries.
