Hey! Relax creator here. You're absolutely right, although Relax stays in between that problem. Each component can have styles, and these styles will come alongside a theme. Which means if the end user is using a theme, he'll just have to drag and drop components, and select the style from the ones the theme has. Makes sense?
We'll also have a templates feature which users can use to not start a page from scratch :-)
