I believe the grandparent post is referring to the fact that HFS+ is available in the open source release of xnu [1] while the question of whether Apple will open source APFS kext, especially given their recent trend of moving functionality from xnu into closed source kexts.

I think it would be smart for them to open source it, if not simply for the interoperability use cases.

Yep. So far, they've committed to publishing "the APFS volume format" [1]. It'll be interesting if they fold it back (into the kernel proper) as part of making APFS bootable.
