What's up is that most people don't want a big breaker panel in a room they spend time in. It's ugly.
Sticking the panel in a closet doesn't work, because it generally violates codes twice, once for the fact that all the clothes/random junk in the closet blocks access to the panel, and a second time for the fact that even empty, most closets don't provide sufficient clearance all around the panel to meet code requirements.
If I were building a new house, I'd consider putting the panel on the main floor and just hanging a big painting to hide it (which still violates code, but it's pretty trivial to take down a painting).
