Well, from the productivity standpoint, writing your own hamburger menu's and making them all appear correctly on mobile, tablet and others...
Making the sidebars, dropdown components that work on mobile correctly, and all the other things that a simple app might need.
Rewriting these things instead of using the framework is almost the same as inventing the wheel all over again. I use Bulma, which is lighter and more opinionated than Bootstrap, doesn't provide atomic classes, and anything on that level of case-to-case usage. But it does provide modules that you won't use on a simple website.
Anything beyond a landing page requires an efficient developer to use a framework. Especially when you are working alone on the project, playing around with hamburger menus is just a plain waste of time.

I totally agree on everything you said! That's why I said that if you want to develop something fast you can totally use Bootstrap!
