I can imagine having every ELF file on Fedora define a symbol like
encodes the name and version of the package it came from would be
rather annoying.  If nothing else, it's entirely possible that two
different .so files in the same package would then define the same
symbol.  This would, if nothing else, be rather confusing IMO.  But
I'm not in charge of Fedora packaging.
