You are suggesting that soldering, although more time consuming and
expensive, would be better for longer-life applications.

Back in the early 60s, I worked with an engineer that needed to
determine which type of connection would be best for use in a
high-reliability military system.

Half of several connector sets were soldered, half were crimped. This
included using smaller gauge wire in some pins, folding the wire for
crimping.

My job was to monitor the testing, which included vibration, shock,
temperature cycling, humidity cycling and salt spray.

As I recall, there were numerous failures of the soldered connections.
The only crimp failures were where smaller gauge wire was used.
