No, it isn't.

ELF shared libraries were designed to be an optimization of the
traditional archives created by ar.  They do not achieve that in every
respect.  But that is the goal.  Historically speaking, ELF shared
libraries are a reworking of SunOS shared libraries.

You can use version scripts to turn shared libraries into something
like a namespace.  But version scripts are a relatively new addition
to ELF shared libraries.
