so if you want to copy a particular set of files (owned by several users) and
you want to have the same permissions on the receiver side you must set the
permission of the root to the same as it was (and when newly created).
Otherwise you may also make the copy unavailable to the original user.
It is not related anyhow to the --relative flag.
Noone requested it to be mandatory, it would be much better to implement a new
flag. By default it will do nothing (like now), but by setting it rsync will
take care of a few more permissions.
To implement this feature outside of rsync will degrade the performance of the
syncing process significantly.
