I think you've just described the difference between a dev tree, and a 
stable tree.

Committing to a stable tree should involve quite a bit of thought, and 
checking to make sure everything is correct. For me, a dev tree is just 
that. Something where I'm doing development, and don't even make the 
guarantee that it will compile.

I might be a little unique in this, since I tend to work from multiple 
machines, and I use revision control to move between them (used to use 
CVS, now arch). So frequently not only are my programs broken, but they 
won't even compile. But that's why there is a dev branch, and a 
mainline/stable branch. For a lot of my stuff, there is only a dev 
branch, because it's not worth the overhead of stable if I'm the only 
one using it.

But if you really want "this tree is always good", you probably want 
something more like a stable branch, rather than trying to do that with 
your dev branch.

arch makes creating and maintaining concurrent branches very easy. Might 
as well put that to good use.
