I've wondered the same thing.
I use three NLEs, Sony's PlayMemories Home, Panasonic's HDWriter and Adobe's Premier Elements. I've also used Sony's Movie Studio and Windows Movie Maker. The first two can do lossless editing. The rest can't.
I think there may be three reasons most NLEs don't include lossless (smart or dumb) rendering.
First, most people don't want it, except for very small group of "purests" that get their video watching pleasure in seeing perfect 1080p60 footage. When I use my two lossless NLEs, I have to make extra effort to watch it! It is fun, but I have to find a way to play it. I have to put it on some sort of specialty device to get it to the TV. Most people don't want to go through the special steps or own the devices.
Second, the common viewing methods of DVD players, Blu-Ray players, computer screens, tablets and smartphones have to have the 1080p60 footage translated somehow. Throw in YouTube and Vimeo as delivery circuits and it gets worse. Trying to reach even the smallest audience with lossless footage is impossible.
Third is the creative process. Editing is not lossless. It is additive. In the process of turning footage into a video, or movie, the person editing adds creativity in the form of titles, transitions, audio effects, video effects, color adjustments, etc. The combined additions improve the video. It is not just video editing. With all digital graphic arts, the post processing is as important as the capturing. In one fascinating forum elsewhere, a member posts an unretouched "lossless" photo. Other members go to work on it, and a day or so later, they post what they were able to accomplish and explain how. Last week I saw a pretty good portrait of a young girl turn into a dozen versions of a extraordinarily beautiful woman. Watch any hollywood movie twice. Enjoy the story the first time. The second time, watch it for post processing editing techniques.
I recently completed an arduous 70 minute family reunion and history documentary. The reality is that to share it with the family members in four states, it has to end up as a DVD and Blu-Ray. A lossless NLE was useless. To get the primary star remotely interesting required a lot of additive editing followed by rendering or transcoding to practical media.
Lossless editing, except for certain minor exceptions, is practically useless. Creative, or "additive" editing is difficult to learn. It is a bigger challenge than gluing clips together that play like a slide show with motion.
