This is a bit hard to do and also it doesn’t really match this lib’s philosophy because breakpoints overlap each other.
Let’s say that the breakpoint related to the current viewport is md, smUp, xsUp, mdUp, md, mdDown, lgDown and xlDown will all match this viewport.
We could say “Okay but if we don’t consider the Ups and Downs, we could have a 1-1 binding”. But this couldn’t work either with custom breakpoints. Anyone could have a phone breakpoint that goes from 200px to 700px, a tablet breakpoint that goes from 500px to 1100px etc. And in this case, a viewport of 600px doesn’t match a unique breakpoint.
That’s why the hook useBreakpoint was created.
