RSC polish at service - or not?

I'm getting ready to send in my 2008 16610LN for RSC service. Nothing is wrong other than it is 15 yrs old and has gotten the majority of wrist time over the last 10 yrs or so (lately been mixing it up a bit more with the others). It's running right around +6 secs/24 hrs - so just about on the upper end of the spec. I know some will say it doesn;t need service, and others will. I'd prefer not to wear it until something breaks as that tends to be more expensive (generally I think). Overall, it is in excellent condition without major scratches/gouges etc. So, I'm inclined to say no to having them polish it - what say you?
