Thanks for the nice analysis.

Yeah, I suspect this worked at one time, given there is dedicated
handling of IDs in org-clone-subtree-with-time-shift.
[... bisecting ...]
The failure started with 9865e6bd8 (org-id: Speedup, minor functional
change and fix, 2019-08-01), which was part of the 9.3 release.
Interestingly that seems to be functionally equivalent to what you
mentioned next:

That sounds right, so it seems it was just broken in a quieter way
before.

Hmm, that should indeed work, but I'd be leery of it introducing other
bugs and complications. How about something like this?

Subject: [PATCH] org-id: Allow file name to be overridden on ID creation
* lisp/org-id.el (org-id-overriding-file-name): New variable.
(org-id-get): Prefer org-id-overriding-file-name over the buffer's
file name if set.
(org-id-locations-load): Give a more informative error when file is
nil.
* lisp/org.el (org-clone-subtree-with-time-shift): Let-bind
org-id-overriding-file-name, enabling an ID to be created for a cloned
subtree rather than crashing with a type error.
Note that, before 9865e6bd8 (org-id: Speedup, minor functional change
and fix, 2019-08-01), this wouldn't fail with a type error. However,
the ID would not be added correctly because org-id-add-location simply
wouldn't process the id at all if the passed file was nil.
