This is a replacement for `std::any` until such time that we have C++17.  While I generally agree it should not be used, and usually you want something like a variant, there are still occasions where it can be useful.  One example is where a user wants to attach some user data to a structure that passes through library code and comes back around through a callback or similar mechanism.  Another is when porting old-style C code that uses `void*`.  I'm sure we can come up with plenty of other uses as well.
