That is to say, I have an async transaction which is resumed in an async worker and is t_relay()’d away to some destination. Meanwhile, I have learned about new destinations for it to try via an incoming registration, and would like to append additional parallel forking branches to that transaction, even though it is already proceeding. ts_append() does this for me; the issue I have is that it is mediated through a registrar, but I am not a registrar. My registrar is upstream, and my proxy is just a front-end to it. So, in essence, I require something like `tsilo` at a more general level, where contacts can be populated by some other mechanism rather than being learned via callbacks out of `usrloc`. Is there a way to accomplish this?
