For example if you watch the Albion "how its made" video and listen to many other bladesmiths they say they use a concentrated gas torch on the end of the tang and peen like that. That way they don't spread heat through the blade and destroy the post-quench hardness.

I've heard both cold peening and hot penning are historically accurate (true/false?), if so, how did a medieval swordsmith manage a hot peen? They were working with large, well-dissipated heat sources, nothing that could heat a 1-3 inch spot to forging temps while the rest of the sword remained room temperature.

Itīs no problem really.
Deflect the heat from the areas you donīt want to heat.
A piece of thick sheat Iron for example.
And wrap the areas you donīt want to heat in wet cloth and work fast.

So the heat doesn't "conduct" down the blade much?

Even with my 3/4" burners propane forge I worry about undesired tempering in steel within proximity to a 'hot spot' I'm doing

It seems like it would be really difficult in a coal or similar forge, back in the day

The wet cloth is definitely a good idea, I must try that

Heating the last inch or so of the tang in a coal fire without significantly the rest of the blade is no problem. The steel conducts heat, but not very quickly. Heating a plain carbon steel upto 200C (418 fF) or so will not significantly mess with the temper.

Another thing to consider: a little heat in the tang might soften that area in a beneficial way. Some tangs were less hard, unhardened altogether, or even made of softer iron.
