So even if the right thing to do is to add the function at the C-level we still need to think about 21.4. So we will need the compatibility stuff in e-lisp too. Still this doesn't answer whether we should solve incompatibilities based on the experience gained when upgrading packages or if we should to through the APIs in a more structured way.
