Test case

Save any kind of model twice.

Steps to reproduce

Save any kind of model twice.

Expected behavior

Not observer should be called ( or property update ) on the second save, since no value have been changed.

Actual behavior

Observer are triggered, which make everything either very slow or not practical at all. You multiply that by the fact that relationships are saved on a different pass, and you obtain a callback nightmare.
