TL;DR: kernels aren't numbered in a suitable way. On Debian for example, packages like linux-image-amd64 are versioned with the full kernel version - eg: 6.12.73-1, or 7.0.4-1~bpo13+1. Getting the conflicts or depends correct under all circumstances is nontrivial, as you can't wildcard them. (Yes, it's *possible* with hacks like "< 6.19.999", but one needs to consider the tradeoffs between this kind of dependency and the possibility of edge case breakage when something unexpected happens upstream.)

An easier approach, for what it's worth, is what I do - instead of installing linux-image-amd64, I maintain a local package "zfs-linux-image-amd64" which strictly depends on specific kernel and zfs-dkms | zfs-modules versions. This is pulled in from my local repository, and ensures that no upgrades happen until I've validated that they work.
