Yes it is. The only reason it wasn't supported in the first place is because of the GRUB ZFS implementation, which must be able to read the entire kernel & boot archive from a single physical drive. Neither the slog nor the l2cache devices are needed for that, hence why you can use them. Same thing with mirror vdevs (all drives contain the a full copy of the kernel & boot archive).
