Photoshop: an option to disable Sub-Pixel guide positions

Something that has really bothered me about recent versions of Photoshop (CS5 / CS5.5) is that the now default behavior of guide-dragging is to allow guides to be placed anywhere they happen to fall. The most annoying part is that it seems to be a very meticulous and sometimes impossible task to get guides to always snap to whole pixel values. (e.g. you can hold shift while zoomed in to 500% while using pixel guides, but some times I've noticed that while zoomed in that far on a complex image with many layers, the guide system simply ceases to function).

If you ask me, I really see no reason anybody would ever even want to have a guide placed -inside- of a pixel. The only things those types of guides seem useful for are making your image re-sample when you crop snapped to that guide, or drawing blurry lines while your pencil snaps to that guide.

I just tried out the beta of CS6, and while overall, I was very happy with the experience, I was still disappointed to see yet nothing addressing this problem. (It seems a common concern around the internet.)

I was however happy to see this option in the General Preferences page:
'Snap Vector Tools and Transforms to Pixel Grid'

This option allows vector and transform tools to function in exactly the way I usually want to use guides while dragging.

I think it would be a great addition to add a second check-box under this option:

Physical measurements (inches, meters, columns, etc.) don't always fall on a whole pixel, and thus need guides placed at specific locations that are not whole pixel increments.

UI and Web designers tend to think in whole pixels, and they might use such an option (until they start thinking about resizable UI that won't have a specific pixel count).
