No, it has not.

In fact, it is only on PC like hardware that you can reliably share
a disk between different mutually competitive operating systems.

Most "unix-machines" don't have a concept of what you call partitions,
and neither did BSD unix until 386BSD introduced it.

Until then: One OS, one disk(-pack|-drive).
