I've done that for desktop apps before. You have to be careful with the effects of sub-pixel rendering and whatnot if your math is continuous, but it's a viable path that I quite like.
Don't use continuous math in either a design system nor a constraint solver that you expect random developers to use. Either case will only lead to problems.
