These are great questions 
One clarification - Agency is only referenced here as they’ll be allocated $1k monthly to work on the DAOs website. They are forming their own sub-dao, see [DRAFT] Agency Sub-DAO
At a high level, I’d like to see more independent Sub-DAOs that can create value, with some of that being returned to the DAO so Members can re-allocate that value to support others to do so their own thing. Over the next few weeks/months, it will be interesting to see what makes sense to stay in Labs vs being spun out.
Regarding overlap between Stewards / Labs - I agree with @wolovim that we will likely encounter issues. his season which we’ll need to iron out. The Stewards role is quite a lot of effort and responsibility for (currently) very little reward, so it’s not surprising there is a big overlap. In an ideal world we’d reward everyone in a meaningful way but the treasury is just not large enough yet.
one out come of this budgeting process for me at least is reviewing how we’re calculating rewards both [DRAFT] Rewarding Contributions in $CODE and other assets.
