Clarify if orphan

to address #4717

Please check the accuracy of this when you get a chance, @msullivan. I'm particularly concerned if I properly understand the implications I've described in the second paragraph of my note.

If my description is accurate, I wonder if we can and should consider another way to handle beyond just documenting it as-is. I feel like the result I've described would be fairly surprising.

[msullivan]

Yeah, that is all correct

[msullivan]

We definitely could implement the other behavior.

I believe that Elvis was concerned about the performance implications, though it might not be that bad: we have to do the exact same checks when we actually do delete an object as we do to check if it is an orphan...

Thanks for checking this, @msullivan. Glad to have it documented.

Maybe it's worthwhile to discuss whether changing the behavior or maybe offering both (if local orphan/if global orphan or something like that) would be worth the trade-off.
