the interface always sets "{endpoint_name}.database.changed" even when nothing has changed

Hi,

requires.py does the following :

392 @when_not('endpoint.{endpoint_name}.joined')
393 def _departed(self):
394 self._clear_all_flags()
395 self._clear_flag('{endpoint_name}.database.changed')
396 self._set_flag('{endpoint_name}.database.changed')
397 self._clear_flag('{endpoint_name}.master.changed')
398 self._set_flag('{endpoint_name}.master.changed')
399 self._clear_flag('{endpoint_name}.standbys.changed')
400 self._set_flag('{endpoint_name}.standbys.changed')

meaning that when the relation is torn down, every hook invocation will have the .changed flags set, even though nothing changed (after the first hook runs). This is misleading / not really usable.

Thanks
