It's not a necessity....BUT, its one of those things where it'll just start to leak when it decides it wants to leak. I've done them before, smearing some hylomar on the metal P-gasket before installing and it certainly gives peace of mind, but *generally* when they fail it's not a catastrophic thing but more of a weep/drip so you should have some forewarning. That said, it could also be a "while you're in there thing" if you wanted to bang (no pun intended!) it out.
