I've checked the README again, and I think that for the reason's above it should be retained as-is in `libcrexec`/`libcriuengine`, rather than in libcrcommon. I can add a README into `libsimengine` saying that the format should be the same as `libcrexec`, but the existence of `libcrcommon` is an implementation detail, rather than something user-facing.
