They always taught us in electronics schools, "Make a secure mechanical-wrap
before soldering; solder isn't glue."

Oddly this is actually incorrect. Yep, they taught the wrong
thing, but it is so widely accepted nobody ever questions the
mil-spec 'wrap three times before soldering' approach.

To convince yourself otherwise, make a simple lap joint using
stranded wire, with the lap being only two or three wire
diameters. Copper wire of course.

Then tension the joint until it fails by pulling on the wire
ends.

The joint does not come apart, even with standard 60/40 lead tin
solder.
