I beg to disagree, Julerz escrowed bounty tokens for bounty hunters and all bounty hunters have received their tokens, some managers are escrowing the bounty token which is good, but if the team is trusted and they show good will it's ok not to do escrow especially if the bounty manager is part of the team, like what Oikos has done.
Only few projects are doing an escrowed for token payment. We are lucky that we have those doing that like Julerz and Bounty Detective, but as you said, as long as the team is trusted no need for escrow.
One example is cartesi by BubbleAlex, he did not escrow the bounty but the team paid their dues to hunter. Sometime it actually depends on the project if its good then no need to worry about it. Unless you are joining a bitcoin sig paid campaign.
