Nigel Jones commented on ATLAS-1175:
------------------------------------
To avoid resurfacing old values doing the "cleanup" of any entities (ie
removing the relevant attribute value) needs to be done with care. Doing it
synchronously could be a performance impact for a system with many entities. I
think it would be need to be done asynchronously, or potentially could be
self-corrected during a future read or update of the entity (this is where
integrating such a change in with versioning as david mentioned in ATLAS-1174
may help?)
> Type updates should allow removal of optional attributes
