Sigh... OK, I really need more coffee. Let me put it that way: this
behaviour (names migrating as the result of operation on different names)
has really nasty implications. On VFAT we had it due to short names. Your
proposal on NTFS promises the same sort of fun. Experience from dealing
with the shortname problems on VFAT makes me rather unhappy about your
proposal.

They are _not_ distinct in the beginning. OK, NTFS is claimed to support
links. I bet that they apply to the whole bunch of forks/whatever, not to
the individual components. rename() will do...?

Are there separate permissions/ownership on these beasts? Welcome to fun
with rename() that happens to split them (and that will be any rename in
your variant).
