It's not expected to be written out, yet it's harmless otherwise. That 
attribute has always been there, just hidden. It looks like an 
incomplete backport of internal refactoring from v3 made it through to 
2.0.11 and this attribute got unwantedly unhidden.

Sorry for the inconvenience. Please ignore that attribute for now.
