The rationale (from http://wiki.debian.org/ToolChain/DSOLinking)
is to detect situations where
your executable links against a library A which links against
library B, but your executable needs symbols in library B. This is
problematic in the situation where library A removes its
dependency to library B. The next time the executable gets rebuild
it will break and cannot be linked.
I think that pkg-config style dependency information is also helpful
for people using static linking.
