It isn't an oversight. It's on my ToDo list (and this item is an action
item on the wiki as well). We had the Thanksgiving holiday; then I was out
last week at AdhearsionConf (great conference!). The licensing file will
get updated before 12 is released.

As an aside, we also had conversations about it on the asterisk-app-dev
list [1], where I responded that I would get answers to the licensing
questions. Granted, it has been much longer than a week or two - mea culpa
on a bad time estimate.
