Au contraire.
Unless its philosophy has changed, BMW's recommendation has always been for dry slide pins (and spark plug threads).
They do call for plastilube on the ears and backing plate area, which is why they go to the trouble of making it available in small packets. The TIS is very clear on where it should be applied.
But it is not rubber safe, and not to be applied to those parts of the caliper, which also makes it unsuitable for caliper rebuilds, despite what some parts suppliers imply in their product listings for it.
Sil-Glide is mentioned often, and I use it, but it definitely has its limitations.
Despite its name, it's castor oil, not silicone based. And I don't find its durability to be that good. It won't last the life of a set of pads, and it gums up as it ages. I've also tried it on some Toro plastic sprinkler heads, which get sticky as they age and don't extend fully. It works as intended when first applied, but such a wet environment illustrates how quickly it can be diminished.
As a rubber and plastic safe lube, I guess it's ok because it's cheap and easy to find. But there are probably better products out there.
