I mean, usually people should have linux-image-<version> installed, not linux-image-unsigned - they are basically only artifacts used for building the signed kernel images that are installed by the metapackages.

Since there is no metapackage that pulls in unsigned kernels, there is no reason to add unsigned kernels to that list, as they'll be manually installed anyway.
