You are correct, but I think we're lacking in things even more basic than that.
Pretty much every single responsive design I ever worked had either the mobile or desktop version as an afterthought. The mobile was just a "scaled down" version that was done last-minute, or vice versa.
Is there a sidebar? Hamburger menu it is. Is there a list? Well just put every row on top of each other.
Sure, this makes things easier for the both the designer and the developers, but putting just a bit more effort in the "secondary" version would be enough to make both versions better.
