Imho, clearfix as a solution to a problem that existed before CSS3, when people used the `float` role to align things in a row -- when time came to stop the alignment behavior, you applied a clearfix. Today, you really only float things that have a block flow inside an inline context, like asides, pictures, blockquotes, etc. You don't really need clearfix since your inline content should just flow around it. If you are using floats on entire sections you are obviously doing something wrong, and you ought to ask your self if `display: flex` on the parent wouldn't be a better fit.
