It sure is.

There was a suggestion from the systemd folks to bump the kernel
protocol major version to 6 and add a packed structure for use with that
version and beyond. That's a bit ugly too but won't break things that
already work around it in user space for major version 5 and avoids.

I've not got around to checking if the patch works correctly and
finishing it.
