Does that mean they used solder on 100's of thousands of miles of wire
when only a teeny tiny bit ever appeared out of the insulation? Isn't
that a big waste of tin and lead? Do they still do that?

Yes, it is one of the ways that "marine grade" wire is made more
expensive! The idea is that at sea you cannot guarantee that bare copper
wire will be protected from corrosion by the insulation.



some military grade wires are "made more expensive" by being silver
plated - although they might look like they are tinned.

Also, the insulation is often of teflon instead of PVC
