[O] Should a human ever set the ID property? Should a human only ever set the CUSTOM_ID property?

[Grant Rettke]

Good evening,

Just learned about CUSTOM_ID property. It seems like if you want to
define a custom identifier, then you do it here and that identifier
will get used correctly in all of the weavers. It also seems like a
human should never set the value of the ID property.

The reason I ask is that I've got code that makes sure that every
headline has an ID property set unique because org-uuid makes it so
easy. At the time CUSTOM_ID didn't exist. It kind of looks like I
ought to refactor all of it to use CUSTOM_ID because it will "just
work" in the rest of org mode.

Am I grokking things correctly here?

Sincerely,

Grant Rettke
