I'm sorry Ben but I don't get this logic at all. How come it has never been a problem in Adobe Illustrator or any graphic design software I used? Whatever happens regarding selection should be taken care under the hood, we just don't want to have selecting objects as part of undo history, because when we click somewhere else and deselect an object, we loose the ability to redo commands that happened later. Object selection is not an action I care about. When I hit "undo" that means I want to undo certain changes I made, not to deselect an object! If I wanted to deselect an object, I'd simply click anywhere outside of it or selected another object. 
 
It looks like you're trying to reinvent the wheel. I've never encounter such counterproductive solution in any other software. Undo should undo recent command applied, not recent command applied to a "selection". 

I personally dislike the status quo because I cannot quickly toggle between a before and after to see the change made without the bounding box or curves being in the way since they are always selected. And, as @Bauke said, if you deselect, the future action is erased. Sometimes the change is subtle, and those extra selection lines are frankly annoying at these times.
 
Might it be possible to differentiate making a selection with a dedicated selection tool versus the move and other multi-use or irrelevant tools, so that history of purposeful and potentially detailed selections are the only ones recorded? (This should also solve the macro issue as well if I understand it correctly.) I can certainly see the value in being able to recover manual selections, but not automatic ones, like bounding boxes, curves, etc, if you'll allow that distinction.

Hi, I have the same problem here and it would be great if you could solve the problem. It's really frustrating if you can't do a "redo" because of unselecting an object.
