Our current plan is to put CCAO in a branch based on the final 1.8. The team consensus is that the jsdoc comments and in particular the inline type annotations make the code much less readable. Some of the CCAO code changes may be pulled into master, but in total they are 200 bytes so it's unlikely we will pull them all in.
For this to progress further after 1.8, we will require community assistance to help maintain CCAO compatibility and provide help for users wanting to build their own projects with jQuery and CCAO (see the task list above). If there is sufficient interest and participation, we will consider further integration.
