For connections that really matter, I do exactly the same as you do -- especially in a high-vibration environment.
Peace of mind is sometimes worth the hassle.
Apart from that, correct sizing of the wire and insulation to the terminal is important.
Equally important, is to use the correct crimping tool.
And, at some point near the connection is some sort of strain-relief.
Sorry, no magic fix.
(for automotive applications, I've used 'trailer-style' rubber encased connectors which come pre-terminated with about 6" of wire. They come in 4, 6, ..circuits)
