I had in mind a stricter definition that takes semantics into account. For
example if a method breaks its contract by changing its behaviour then it
may be a new ABI, even if the method signature is the same.

Then we cannot prevent a library from being upgraded to an incompatible
version, as in the Tomcat breakage that was reported to the list just the
other day. That should prove that we do need ABI information.

Also there are packages that don't have test suites, or that don't run them
at build time.
