9.0.0 segmentation and line breaks on the empty string

I notice that in 9.0.0, UAX29 segmentations no longer report boundaries on the empty string while UAX14 still does report a hard line break on it. Is this intended ? and what is the rationale behind these changes and non-changes ? 

While I think that the proposed UAX29 is a better one, these kind of changes on special cases make it easy to break assumptions made by client code so it would be better if these things do not change to often. Hence my request, shouldn't UAX14 also report no breaks on the empty string ?
