The behavior of all this setAttributes function seems like something that should be absorbed in the updateBlockAttributes action instead.

As you said, we should ship the bug fix and consider these consolidations separately.

Yes, I think so too. One point of clarification / affirmation is that: I don't think the changes here dig us any further into a hole, and in-fact serve more as an implementation which ought to have existed in the first place.

return get( type, [ 'attributes', key, 'source' ] ) === 'meta';
}

// Partition new attributes to delegate update behavior by source.
//
// TODO: A consolidated approach to external attributes sourcing
// should be devised to avoid specific handling for meta, enable
// additional attributes sources.
