That actually might be nice but don't get your hopes up, systemd isn't actually part of the linux kernel as some conspiracy nuts would have you believe. The systemd project can't possibly just add random stuff to kernel panics, all of that code is in the kernel, not userspace.
I think a little while ago there actually was some work done on making kernel panics display a QR code but I doubt it'll ever be merged in if it's even done.
