My biggest gripe concerning Bootstrap is that it's listed as a project requirement, for whatever reason, and the designers refuse to design according to Bootstrap standards. For me that's been the main reason of having to tweak the defaults beyond their original intent. It can eventually reach a point where it's better to dump Bootstrap and build from scratch. As for Bootstrap's grid system and nesting grids: I would think all grid systems work this way. I'm not sure how it would work otherwise. It's the same as nesting tables, you'll run into problems if you aren't careful and plan ahead. I would imagine in many ways that nested grid may not actually need to be a grid based on the purpose of Bootstrap's grid system. I bet a series of inline-block elements would serve the same purpose in many cases.
