> Soldering a crimp really only helps if you've done a poor job of crimping; but it's relatively easy to inspect a crimp. If you solder, you could cause a previously excellent crimped join to be not so great, and it may be hard to see if the crimp opened a bit due to heat, or other things.

Solder joints are also more likely to crack and fail than crimped joints due to vibration. You solder as little as possible in air and space craft.

And much of the soldering is done with solder ferrules (aka solder zaps) that sit over a wire and release solder when exposed to heat. This is all contained in a neat little package. The solder is ultimately connected to a wire that you can then run to a connector. This is how we usually will connect a braided shield to a component ground.
