It is documented as part of the new git-refs(1) man page, in the "Known
limitations" section:
* There is no way to block concurrent writes to the repository during an
ongoing migration. Concurrent writes can lead to an inconsistent migrated
state. Users are expected to block writes on a higher level. If your
repository is registered for scheduled maintenance, it is recommended to
unregister it first with git-maintenance(1).
Is that sufficient, or do you think we need to expand on this?
