When a maintainer is promoting an API to become part of the next major ABI
version by removing the experimental tag, possibly a few releases in
advance of the declaration of the next ABI version. The maintainer may
choose to offer an alias to the experimental tag, as removing the tag
before the declaration of the next major ABI version, would cause an ABI
breakage for applications using the API.
