Well, I thought we have argued about those "shortcomings" back and forth
and expressed that they are not really a problem for workloads which are
going to use the feature. The backward compatibility has been explained
as well AFAICT. Anyway if this is your position on the matter then I
just give up. I've tried to do my best to review the feature (as !author
nor the end user) and I cannot do really much more. I find it quite sad
though to be honest.
