You're correct that the ABI version can change, but the process is to make an
update to doc/guides/rel_notes/abi.rst documenting the proposed changed, wait
for that to be published in an official release, then make the change for the
following release.  That way downstream adopters have some lead time to prep for
upstream changes.
