Lightroom/ACR: Don't remove manual Chromatic Aberration and Defringe capability

I love Lightroom 3, and Adobe products in general, but I'm very disappointed in the loss of control I have over Chromatic Aberration and Defringing in the Lightroom 4 beta, as compared to LIghtroom 3.

I miss the CA slider on the Profile tab, and also the Red/Cyan and Blue/Yellow sliders on the manual tab. Is there any chance we can have them back? Auto is good when it works, but I shoot RAW and use Lightroom because I can often get better results by doing some things manually. I also use Lightroom for editing images taken with lenses that don't have profiles, including manual focus lenses that don't tell the camera what the focus distance is and a great manual-focus zoom that doesn't provide focal length info. I also use it for non-destructively editing images scanned from film. Having manual control of CA and fringing is important to me.

This new version also seems to weaken the Defringe function. It just doesn't go nearly far enough to remove fringing from many of my photos, like older ones shot on my D70/18-200mm combo, for example. I've gone back and forth between versions, and Lightroom 3 does a much better job for me.

If you really want to turn my frown upside down, instead of a defringe check-box, could we have a slider? Or ideally even a few sliders, so we could control color fringing similar to what can be done with the sharpening controls: in terms of strength, but also how contrasty an edge needs to be before it is affected by defringing, and the radius the of effect. Could we have a defringe function on the adjustment brush, or have separate control of magenta and teal fringing?

Thank you for your great products and continual improvements. I will still buy Photoshop no matter how great Lightroom becomes.
