It should be noted that (for Nodes) id + version is actually stable (Ways and Relations are more complicated).
So if you have id + version, you can - check that it is the current version of the object (all fine and dandy) - check if there is a later (undeleted) version, check if it (depending on your criteria) is still the "same object", update version in your reference - if the last version is deleted or your criteria for it being the same object doesn't hold, search in the vicinity for a replacement object. Doing the same for Ways and Relations requires including a location reference of some kind as geometry changes are not reflected in the versions, but can work in principle the same.
