If I can’t turn left due to weather I inform tower before accepting a TO clearance. The weather overlay seems to show no weather issues with a left turn and flights before and after had no issues. North of LGA and JFK was getting hammered which would make the southern area extremely busy airspace. I doubt the vectors were for spite and they probably had to suspend departures from 31L or LGA depending on configuration. NYC atc has very good weather overlays and they discontinue departures quickly when weather blocks a route. They also provide calls as to WX intensity ahead on a routine baises. They use terminology level 1 through 6 precipitation.
You can make some inference from Delta 191 at DFW but it’s slight at best. One was a aircraft in approach configuration at low altitude descending at minimum speed and the other was a clean aircraft climbing at a much higher altitude and speed. From a safety standpoint a apples to oranges situation.
The reference to DL191 was to illustrate the sudden changes in convective weather. A Learjet flew through the weather shortly before and survived but the heavy behind it didn’t as it was hit by a microburst.
