Let's suppose you adjust your DA to meet Missed approach climb req's OEI then Some light twins would have a MAPt back out near the OM.
Cs Approach tend to give departing aircraft assigned 030, so the missed approach tK 015 will keep you clear of departing aircraft, and the earlier it's initiated the more separation you will get.
I'm in the "turn as soon as it gets hairy" camp but welcome being proved wrong.
