Why navbar items (dropdowns) cannot be open on hover?

I understand mobile first, but bootstrap is used in many products and not only for mobile applications and such a simple things as opening menu items on mouse over on desktop should be available by default (or with simple class switch) without using external scripts like:

This is basic stuff and it's such a standard UX feature for web pages on desktop that by not including it you're confusing end users used to this behaviour on desktop.
