This is indeed true, and can cause problems with ping/detonation. However, these distributors come with an *adjustable* vacuum advance -- so an afternoon's worth of driving and tweaking with an allen wrench will let you set it just right. You'll have a little more zip when you need it, but no ping. :o) I've been driving my '71 Imperial with one of these systems for six years now -- no problems whatsoever and great throttle response (I'd also say better cold starts and improved fuel economy too).
