But the only thing I can do once this change is made in a UA is to remove all instances of linear-gradient from my site for that UA, and then wait a year or more for the people who use the older version to drop to inconsequential numbers.

So you are anticipating Chrome and Firefox wouldnt change until the prefix is dropped, that I would write my stylesheets with a list of prefixed versions followed by an unprefixed version having a different value? Because that's more intuitive and will lead to fewer author mistakes? Really?

And if Safari changes right away, while Chrome waits until CR, then which value do I use for my Webkit prefixed version. 

One of the reasons for having experimental properties and values is to gain author experience in the wild. This will have an opposite effect.
