Comment 6 for bug 1531128

AFAIC, 'nodes' data is skipped by the manifests (after according change to the library) and deployment tasks utilizing the info has type skipped [1] for releases >= 9.0 (thus is not processed by the Nailgun). All that implies that serialization of the attribute has no real impact on production environment.

However it is hard to introduce the change to Nailgun. Mainly because of this bug [2]; as separate fixture for tests for serializers of versions >= 9.0 must be used and there is no mechanism yet to process such separate fixtures by the testing infrastructure (for more details, please, see description for mentioned related bug).

With that being said the importance of the bug, IMO, should be lowered to medium with all efforts to focus on the related bug.
