Not the user you replied to from my experience usually it's not worth it due to several reasons:

- desoldering the chips takes time and is a manual process ($), with risk of tearing off a pad or bending leads. In case of BGA ICs reballing is needed to reuse them. - components are usually not rated for a lot of reflow (heat/cool) cycles, and some are moisture-sensitive and may crack if they have managed to absorb moisture - you usually end up with some solder and flux left on the IC, which can cause issues - ICs come on tape for feeding into automated pick-and-place machines, so you would need to feed and mount them manually ($)

And if you only realize you have damaged the IC after mounting it on the new board you end up having to rework it again ($).

Sure, it might be worth it if the chip is really expensive or hard to get, or you're soldering everything by hand anyway, but usually the math just doesn't work out.
