I personally do not care a lot about the feature itself. However it's 
unfortunate if it's a MUST in JCR, and a MUST NOT in CMIS.

If it's indeed the case that the majority of the stores can not persist 
empty lists, then the requirement shouldn't have been in JCR in the 
first place. But then, I don't recall that anybody has complained about 
it so far.
