soname changes should happen when binary interfaces are removed or
incompatible.
Bumping on added interface would cause too many unnecessary rebuilds.

Better solution would be versioned symbols (like in glibc, nss or few
other libs), already handled by rpm.

When versioned symbols are not used, %requires_ge_to could be some
solution (also not perfect).

Maintaining symbol lists for rpm automation would require probably too
much effort.

And finally generating per-symbol dependencies would comsume too much
resources.
