What design choice?

1. That `org-find-property' only searches in the current document?

2. That `org-depend-block-todo' uses `org-find-entry-with-id' instead of
   e.g., `org-id-find'?

Property API assumes properties are local to the document. When you
search for property "FOO", it means "FOO" in the current buffer, not
"FOO" is some other random Org file somewhere in your hard-disk.

ID property is special for that matter. Whenever Org sets such
a property, it updates a location database (which means ID properties
shouldn't be changed "manually"). So, ID property can efficiently be
used to refer to remote documents.

As a consequence, it may be useful to use `org-id-find' and fall-back to
`org-find-property' in `org-depend-block-todo'.

I guess nobody. Do you want to take care of it?
