No, there isn't anything I know of.

The kernel boot protocol should probably be extended to accept a block
of values to be passed from the loader to the OS, and be exported
somewhere by the kernel itself to userspace.

Overloading the kernel command line with that does not sound like the
right approach. We should not support anything like that from systemd.
