Arc rotate: dollying and point of interest

Not at all. Just thought you might be overlooking something.
Arc rotate viewing in perspective view can sometimes cause odd results. Thats all.
EDIT: I've always seen the arc rotate as an 'object viewing tool', to 'pan, rotate and scale' your object workspace view. Not as a 'camera'.
I understand the difference in dollying and zooming, but consider those to be camera options, therefore scene mode functions.
So, a misunderstanding, not a belittlement.

I don't think this was an implementation oversight. The purpose is to let the user move both the view's location and pivot point, the same way it does when panning inside the circle. This way you don't have to rotate the view all over the place trying to get the pivot point inside, say, the tip of a finger. Instead you can pan to it and then RMB drag outside the circle until you see the pivot is where you want it. This is spectacular for when working in orthographic views, and I think Steve implemented it with that in mind since ortho is what most users would use. (granted, component framing would render this feature fairly trivial...but still good for tweaking view position)
My suggestion is to use MMB to dolly instead of zoom. That is, it moves the view forward/backward while its pivot point stays in place (as nemyax suggested--visually this only affects perspective view). Retain the RMB-outside-circle functionality for ortho users' benefit and random scenarios for perspective users. Change FOV zoom to shift+MMB (ortho won't have noticeable changes). The only conflict is the camera system in the scene editor--so just make MMB move the camera forward and backward instead of changing the FOV. Camera movement is changed far more often than FOV (or should be, in cinematography), so making MMB move the camera makes sense.

That would be awesome.

Absolutely. I just didn't dare cram two requests into one thread.
Steve:
nemyax: Currently the RMB dollies when dragged up and down outside the circle to the exact point at which the viewer (perspective views) or the camera (camera views) is aiming - the center of the screen. I don't understand how you want this changed.
Update: Do you mean to keep the camera's height above the ground plain constant?
Note: there is a bug in the camera view - the camera's movement isn't changed in the animation keys. But the temporary change in view does what I describe.

No, not the height.
Suppose you framed an object with F in a perspective view. Now dolly away from it and arc rotate the view. In the scheme that I'm proposing, the rotation still happens about the centre of the object (the arc rotation pivot has stayed put). Currently in Anim8or, it happens about a point that's closer to the viewpoint (the arc rotation pivot has dollied along with it).
