ZFS on Linux is not really usable for most users because every kernel update can break your ZFS compatibility.
Meaning unless you want to put in the time to manually test every kernel update and ensure your kernel version stays in-sync with OpenZFS you can very likely end up with an unbootable system.
The 'linux' package on Void is just a meta package. Install whatever kernel series you want. I'm running 6.10.11, with ZFS 2.2.6 on my Void workstation.
