The point here, is "do all this once and at the same time". I plug in my *ist (or SD card), launch the tool, type in the destination folder name and the file name template (for me it's something with the date and subject), and WHAM! i got all shots copied onto my disk, renamed, and so on... I can still come in with bridge afterwards, but those task I always do for all images are done in the process.
I created a little Automator script on Mac OS X that does it all for me. Just tell it what new folder to put the results into and it copies the files to the archive, runs DNG Converter, sets the filenames the way I want them, starts Bridge, adds copyright and creator data, then runs the backup/synchronization utility so everything is ready to be worked on.
All this while I'm away from my desk having a cup of coffee.
However, I count on the fact that CA does not dramatically change over small parameter changes. The most important factor is the focal length, and can be measured on a few values. The software could even interpolate for values not provided. My personal experience with a few lenses is that the AC does not significantly change with the aperture.
I don't find that to be true. CA differences at wide and small aperture are easily seen with most lenses.
I'm not sure about the impact of the subject distance. My guess is that it can be important for Internal Focusing lenses. The EXIF contains some hint of the focusing distance Close/Distant. Let's hope it's sufficient.
Lenses that focus via whole-lens displacement show little CA shift. Rear element and front element focusing lenses see a modest amount of shifting, and lenses with both internal zooming and internal focusing show the most.
