@lftherios currently the Core Development Org would be made up of the following Core Team: Clients, Drips/Funding, Community, Marketing & Ops.
The definition of “core development” could be debated here (i.e. marketing & community are not technically “development”), but even the teams that are not necessarily considered development, they are directly supporting the dev teams. It is arguably more beneficial for these teams to all sit in the same Org and work together on developing strategy, mission, vision, etc.
