I've seen many times in older wiring where the insulation was charred
6-8 inches back from a joint. Must have been a good amount of heat to
do that. If not enough to melt solder, repeated heating/cooling would
probably affect the solder enough to form a cold joint.

Older wiring = 60 deg C insulation at best. That's 180F -- nearly two hundred
degrees below the minimum melting point of tin/lead solder.

I repeat: if your wires get within a hundred degrees of melting the solder,
you have far bigger problems than the solder.
