raspbian is not maintained by Debian, fwiw.
Indirectly it is, since Raspbian uses the unmodified (at least in all cases I'm aware of) Debian package sources and ships the same updates shortly after they have been pushed to the Debian (source) repositories (including debian-security), just build for armv6hf.
But yes, not an issue of Debian where affected users can solve it via backports, if required.
