Feedback - email lists

I am slightly confused as to why we need the 4 default email lists.

What I really want/need is additional lists for our own (mini) working groups.

So I can see all CG participants being on the one list: public-mygroup@w3.org

And then allow additional sub-lists, in our case: public-odrl-version2@w3.org and public-odrl-services@w3.org
which participants have the option of joining (or not)

All lists fall under the CLA.

Am I asking too much?

Cheers
