Hi - I'm a lurker, but I also agree, I feel it's far more intuitive
for the gradient to describe the starting point of the gradient.
Either way, I think it's important to spell out whether it is the
starting point or ending point since there seems to be a lot of
confusion regarding positioning of gradients.

It comes as the first parameter, so logically associates with the start of the gradient. Similarly, in the declaration it comes next to the first color stop, so mentally will be associated with that stop.
