Now we are going back full circles ;-)?

Your earliest attempt indeed copied the above to the code paths used
to handle "--broken", but then Phillip corrected the course

  https://lore.kernel.org/git/054c6ac1-4714-4600-afa5-7e9b6e9b0e72@gmail.com/

to avoid triggering an in-process error and instead run an
equivalent "update-index --refresh" via the run_command() interface,
so that we can catch potential errors.  The code in the more recent
rounds of your patch uses that, no?

Yes, but the cited message above explains the reason why the two
code paths in your patch use different implementations, I would
think.
