Brake Caliper Pistons (To Lube or Not ! !)

During the current crappy UK weather I am taking the opportunity to Service all three Brake Calipers on my Camhead. In the past, and after cleaning all components I have lightly lubed the exposed portions of the Pistons with Silicone grease. I know, some say that this only attracts dust and muck which can cause the very problems which the initial strip and clean was intended to alleviate. What's the current thinking ?.

Never lube them because of the issues you already describe
They aren't lubed from the factory and its not in any part of the servicing on any bike so there is no real need to do it
What is your reasoning for wanting to lube them?

Not sure really, bit over zealous I suppose, and as you rightly point out, it's not a listed service requirement doing so could be detrimental. So then, just a good Caliper and Piston clean with my favourite secret stuff and re-assemble. Those rear pad Springs are a bit hit and miss Heath Robinson affair ! !.
