Hi @Christopher Hoard- Great questions. My understanding is that CSP is a channel that our partner team is investigating and hopes to enable (timing TBD). There is no seat size limit, but customers do need an Enterprise Agreement (which effectively implements a minimum seat size) to purchase licenses. For now, the plan is to continue offering WpA as an add-on for enterprise SKUs (with discount for E5 customers). Of course, that may change as the product and GTM model evolves. Let me know if I can help answer anything else.
