This seems like a pretty major (and gratuitous) change in behaviour. Is
there anyway for an OS to determine whether the command line starts with
the image filename or not? If not then how are OS's expected to cope
with being booted by either Grub-legacy or Grub2?

That may be so, but given that existing OSs (written to conform to the
old behaviour) expect things to be one way, what is the rationale for
changing it?
