linux-image backports metapackage

Hello everybody,

I think I asked this before but I'd like to have both the current stable
and backports kernels installed.

When I upgrade linux-image-amd64 to the backports version the stable kernel
is not upgraded anymore. When I just install the current backports package
directly, like linux-image-6.7.12+bpo-amd64, it stays at that version.

I think (not sure anymore) Ubuntu-backports uses a meta-package
like linux-image-amd64-bookworm-backports.

Wouldn't this be a solution or why would that be a bad/unfeasible idea?

Thank you

Johan
