 But I wonder, what are the possible uses of knowing the return
address?

It is mostly relevant for debuging purposes. 

Function A could contain several calls to function B, and the
return address would reveal which of these calls is active.
It also informs you about what parts of A have been executed so
far, and which remain (assuming no loops :) ).  Even in the
presence of loops in A, it tells you where you currently are
in A.

If you are reaching a breakpoint in B with weird values in
the function parameters, you want to know what code made
that call.
