It's always been first match only, there's no merging.

The best way to do that in V3 (which V2 couldn't do) is with bean inheritance to combine settings. It's not 100% the same but it adresses a lot of the common use cases for merging by putting common settings in a parent bean.

I think we talkd about this on the list a few weeks back.
