Your proposal brings up an interesting comparison between having percentages
refer to the entire length of the gradient and having percentages refer to
the span between lengths. Given this transition (using your proposal):

background: linear-gradient(-70deg / blue 52px, yellow 20%, yellow 80% / red
52px);

In the case where 20% of the entire length of the gradient is less than
52px, is it better to have a hard transition from blue to yellow and yellow
to red, or to maintain blue-yellow/yellow-red gradients within the 52-pixel
solid-color edges? (Clearly, it is NOT good to have the yellow stop precede
the blue and the red stop precede the second yellow.)

There's yet another possibility when percentages refer to the entire
gradient length: should percentages trump <lengths>? (In the above case, the
start and end points would be moved outward. Any span specified with
<length> would be subject to compression.)
