It can be an issue. I deal with this constantly in the leather upholstery business. The problem is not in the leather, it's in the quality of the dyes in the denim. Like most consumer items, there are cheap blue jeans that leach dye and higher quality ones that don't. Because it is a dye, then it can transfer to the leather and cannot be removed short of repainting the leather. If the jeans remain color-fast in the wash, then they have high quality dyes and likely will not bleed onto the leather. But if they are "Cheap Jeans" that lose their color when being washed (Like Levi's) then there will probably be a dye transfer to the seats.
Heat and moisture accelerate the transfer process. Heavy perspiration on a hot summer day - switch to some Khakis until the weather cools. There is nothing that can be put on the seats as a dye transfer barrier short of sitting on a towel or wrapping them in plastic.

So what you're really saying is that we should go with the chalk but I'll tell my wife she's not allowed to wear pants because dye transfer is a risk we don't want to take. Sounds like a plan.
Our Audi has a two-tone interior with light brown seats and I've noticed some dye transfer to the driver's seat from my Levis. Perhaps because I regularly clean the seats and have caught the problem early, I've been able to remove the staining to the point where it's not really noticeable. If they were a really light color like Chalk it might be more of a problem. Personally, I'm not a big fan of very light-colored interiors as they can show any soil and staining more easily, but that's just me.
