You can get the same semantics as for direct binding using symbol versioning, but direct binding is faster.

Also, symbol versioning is only really better than direct binding if you end up having multiple versions of the same symbol provided by the same object, but that's relatively hard to use, so it's really only ever used for things like the C library itself. Mind you, that is a very valuable feature when you need it. In Solaris itself when we needed to deal with the various different behaviors of snprintf() there just wasn't a good way to do it, and only symbol versioning with support for multiple versions of a symbol would have helped.
