I don't want to sound to harsh, but my desktop environment and I know how we want our scrollbars to be and why. Web designers from thousands miles away do not.

I don't want to sound to harsh, but my desktop environment and I know how we want our scrollbars to be and why. Web designers from thousands miles away do not. Furthermore having the need to style scrollbars to make a UX work smells of bad UX design. Given a full screen page, is there really no space for the standard OS scrollbar (or my custom one,) which users see all day long every day they use their computer? Is the OS's UX really so bad that must be improved by a web app? It's wasted designer and developer time.
