GW, 1degree may be 14mm but you have 50mm of movement on the saddle rails. You can use an inline post or one with a little more layback, so you can tweak. How many bikes do you see with 80degree or 60 degree seat angles, These are outside the range that the saddle rails and seatposts can adjust for. There is nothing radical it is tweaks, it is why some people prefer certain frames more than others.
A bike has a job to do, over 100years the geometry and components have developed to the point that the seat angle we have on bikes now suits most people. And whilst the angle at which the tube on the bike is aligned is irrelevant, the angle between the ground the bottom bracket and the saddle that is fairly static.
So sorry your the one talking pish.
