kernel-package is maintained by Manoj Srivastava (cc'd), not by the
Debian kernel team.

kernel-package is not included in stretch at all.  I'm not sure where
you're seeing it as being present on powerpc - that architecture wasn't
included in the stretch release.

kernel-package is currently planned to be included in the next release,
though I'm not sure whether it should be.

There is another bug report about kernel-package with current kernel
versions <https://bugs.debian.org/890817> but I don't know whether it
has been worked around already.
