Unfortunately not everyone in the world can get you to perform their RMS seal change - so they have to rely on themselves or someone else to do it right, and that's taking a chance that it won't be done correctly (as you've pointed out).
So when the RMS wasn't leaking, taking that chance for no extra gain seems a little bold and bordering on foolish.... YMMV
