It's called free insurance.
(or rather, $5.00 insurance).
When you have expensive, valuable hardware, why not take precautions to insure that -nothing- goes wrong, when there are no drawbacks to using it?
I actually have a foam dam around my IHS right now since I have conductonaut between IHS and NH-D15, but that's almost 100% required insurance! I also have Super 33+ tape around the socket going to the edge of the IHS, to prevent LM from getting around the edge of the socket also. (the Super 33+ tape is admittedly more important--LM drips off the edge of the IHS and you're in serious trouble).
Now you might scream "paranoid delusions" but have you ever seen those posts with people complaining about thermal paste between the pins? What exactly would you do if that were liquid metal between the pins? How would you get rid of it? I'd rather not take chances.
I have foam dams on everything.
Laptop BGA CPU, Laptop MXM 1070 both LM'd,
Vega 64 and around CPU IHS. That's how I roll.
I even tried to put a foam dam under the IHS for the re-lid, but the space is too small and applies far too much separation pressure on the IHS/package so I gave that up quickly
