Then I guess it's either not used properly most of the time, or hard they make it hard to use it properly. > (for example, by directly referencing > symbols from libb in a's header files).

The liba is not designed properly, it's shouldn't expose that it's using libb. > Extreme example: it is possible that public headers from "a" reference > symbols from "b", but liba itself does not use any symbols from libb, > therefore it does not depend (in the DT_NEEDED sense) on libb at all.
