The exported symbols of a library are part of the ABI but the purpose
of the two tools is completely different.

I don't think so.

debhelper does not have the old binary packages available and isn't a
QA tool anyway. lintian is a QA tool but does not have the old binary
packages available. If we are to do this automatically, we are going
to need a service especially designed for it, possibly based on

You can definitely do that manually and I hope any library maintainers
reading this thread will do so. It might be nice to have a wrapper
script in devscripts to download the relevant binary package versions,
run both tools, generate reports and print any discrepancies. If we
had such a tool, it could be added to check-all-the-things.
