I was wondering if there is any way to make parallel execution of bors try. From what I see, bors relies heavily on trying branch and force pushes stuff there. Is there any way to make that parallelizable? Maybe there is semi documented trying-{pr} template for trying branch or something?
I guess you could manually push to the trying branch which would kick off the workflow, but you won't get notifications in related PRs etc.
Github itself could just kick off a workflow and then another and another (assuming you have no concurrency limitiations).. I'm not sure how much bors needs the current trying commit to be the same through the try.
I wouldn't mind poking at that, but not really sure where to start
