Fuzziness slider for Auto-Mask

Question

The number one way I wreck my images in LR is by using automask with the adjustment brush, and getting harsh transitions where LR decides that a color changes, instead of recognizing it as a gradient, as in the case where an object is partially lit and partially in shadow.
A fuzziness slider could allow the user to adjust fuzziness by Hue or brightness, and thus avoid these ugly transitions.

Then I would argue you STILL do not know how to USE the Auto Mask (and when for what purpose).
The guy who originally worked on Auto Mask was the same guy who wrote the Background Eraser for Photoshop. They operate in a similar manner. What YOU need to do is practice to get the right combination of brush size, feather & flow so you can keep the cursor center always in the color you wish to mask while working the size, feather & flow to already help minimize the amount of cut back that Auto Mask has to do. You also need to work zoomed in enough to localize whatever are you are working on. If you use it correctly, you can produce a remarkably accurate mask but then the question is, what are ya gonna do with it?
There are limits to the strength of the change you can apply in the parameters. You can't paint in a deep blue sky if the sky was burned out to nothing. Using Auto Mask to subtly adjust specific areas that have a substantial difference in tone or color is very easy to do well with practice. And that's all this tool was designed to do.
Camera Raw ain't Photoshop. There are limits to what you can (and WANT to do) in Camera Raw vs. Photoshop. If you need to very accurately mask an area for substantial modification, I wouldn't even bother trying to do it in Camera Raw. If you need to tweak areas that already have enough difference in tone and color to give Auto Mask the teeth to bite into it, sure, go right ahead. In either case, you need to know the tools well enough to know when to use which for what task.
But, proclaiming the tool unusable is a pretty good way of assuring that you will NEVER know how to use itwhile the rest of us learn how and when to use it and therefore benefit from something you gave up on.
