Yes. extList is there for compatibility reasons. The first patches 
removed it, or substituted it with the new array presentation, but 
extensions like phpunit (who directly do something with extList) threw 
warnings then and didn't work anymore.
Therefore, we decided to keep extList, and add extListArray. extList is 
not used in the core anymore, though.
So: It should be ok to manipulate extListArray only, ignoring extList.

It might also be a solution to only write extListArray, and add extList 
transparently to the globals array during bootstrap and mark the 
according code as deprecated.
