Chuck Lorre swears that any show he is involved with, even as far back as Roseanne, never use laugh tracks, and if they can't get an actual audience, they just won't go with any laughter, live or simulated.
Mockumentaries just don't work for television, they just don't. The Christopher Guest movies are fine, it works in that area of entertainment, but it's just not a good idea for TV, and I really don't know who thought it was a brilliant idea to make all new sitcoms like mockumentaries.
But another thing too, TV shows have been doing "cinematic style" production as far back as the 50s, they just weren't done like mockumentaries like today: back then, a television show was produced in two different formats, single-camera, or multi-camera. Most single-camera shows were meant to look cinematic: lots of close-ups and tight shots, quit a bit of tracking shots, being able to arrange a camera set up for a different angle you don't see very often (M*A*S*H was highly praised for their camerawork), and these are the shows that usually had laugh tracks; the multi-camera shows were usually done like stage plays, two cameras to capture the individual characters on the set, and one camera in the middle for a full picture, and these shows mostly had live audiences. It makes sense, the multi-camera shows do a lot of rehearsing, and in most cases, can usually perform the whole episode in only a take or two, which the audience could sit through; the single-camera shows on the other hand, the audience isn't going to want to sit through all the setting up and adjusting camera angles, and see the same shots done over and over again from different camera angles, which is why it was better to use a laugh track on those shows instead.
Some shows tried it out both ways: the first season of The Odd Couple was filmed with one camera, cinematic style, with just a laugh track, but the actors disliked working that way, so by the second season, they went with three cameras, did it like a stage play, and had a live audience, with a laugh track only for sweetening. The same can be said for Happy Days, first couple of seasons were single-camera and had a laugh track, but afterwards, they went with three cameras, and a live audience. Heck, even Norman Lear sitcoms, on very rare occasions, also had a laugh track only for sweetening... "The Taxi Caper" episode of All in the Family is a perfect example of this, if you listen carefully, with each genuine audience reaction, you can just make out those old 60s and 70s laugh track laughs mixed in as the audience quiets down.
