Do kilim rugs need a rug pad?

I'm curious to know, when it comes to kilim rugs, is it necessary to use a rug pad underneath? Do they provide better stability, protection, or comfort when placed on a rug pad? Additionally, does the use of a rug pad affect the lifespan of the kilim rug in any way? I'm looking for some insight into the benefits and drawbacks of using a rug pad with kilim rugs.
