I am on the same level as Scot and with the same doubts.
Anyway one more vote to include these improvements to the core repository of
org-mode ASAP.

>>
>> 3 Where can it be tried ?
>> ~~~~~~~~~~~~~~~~~~~~~~~~~~
>>
>> The source is at:
>>
>> git@github.com:ngz/org-mode-lists.git branch: end-lists
>>
>> It is merged very frequently with git head, and I keep a clone of
