Well not really. They aren't in Dressrosa to stop Blackbeard's SAD production. It's Kaido's. The other 3 Yonko probably don't care about DD's resignation from the Shichibukai and BB's only involvement is 1 crew member who probably isn't going to be treated like he needs a babysitter when he commands his own fleet. Law made the alliance for Kaido not the other 3 Yonko, Luffy wants to eventually defeat them all, but right now the focus is on Kaido.
