so if you presumably (probably? possibly?) eliminate
any heat getting to the ic's innards by the method I
described, you're likely doing no damage to it?
The better option is to heat the chip up reasonably slowly - when I
strip a chip from a board (I use a solder pot), I will just warm the
part in question up a bit. When the solder pot hits the pins, the
internal structures of the chip will not get a big jolt. This is quite
similar to how the big pick and place solder machines work on a
factory floor.
Of course the thing to do is to not need to use a pulled part in the
first place, but sometimes that is not really an option with rare
chips. Just keep in mind that a solder pulled chip is a weaker device
than one factory new, and that latent failures lie within.
