(Hi, Dale. Funny how my social circles are overlapping like crazy)

It's really pretty different, and let me explain part of the the problem I
neglected to mention.

The unique IDs are not human-allocated, they are assigned by a GUI
development tool (I don't know what it is and have never seen it). That
means that (1) The wall-clock time between getting the file with the UIDs
and being ready to commit it could be substantial, and (2) if the process
fails because someone else modified the file while they were working, the
developer has to redo all their work from scratch.
