Why aren’t components in DIP package shipped with straight pins?

I've noticed that all DIP packaged devices have pins which are at an angle other than 90∘ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that? 

I’m pretty sure that auto-insertion machines expect to set pins to the desired orientation by pushing in on them from the outside.

If the part is gripped from the outside and squeezed just far enough for the pins to enter the holes, while the part is being squeezed, the elasticity of the pins will usually cause it to “grip” the holes as soon as they’re released. Such gripping behavior may help keep the parts from being dislodged before wave soldering is complete.

Do modern LED lights use thermal vias?

I have a technical question about thermal management with mid-power LED diodes.Do you use thermal vias on the PC board anymore? Either under the LED diode footprint or even around the footprint?
Depends on the application limits and cost targets.
