The reason for these is that a revision number is nothing more than a
reference point to a status of the repository at a certain date/time.
If you do a partial load, you are only keeping certain markers for those
points in time. Since the system has no idea of what has happened to
anything that is not being imported, it would make no sense to keep the
original numbering. You might forget that numbers were skipped, or why
(based on the load filter), or some new person may come in behind you.

To a lay person (me), the revision is nothing more than a sequential
number to correlate to the date/time stamp being created with that revision.
