There are many times, most often while I am either double clicking to get into isolation mode, or selecting a layer as I am moving the mouse, where I accidentally move the object I clicked on a tiny bit, this becomes a problem on some pieces of artwork where math and/or high level accuracy are involved, and the adjustments are so minimal that they aren't noticed until its too late to undo.

It would be really cool if illustrator somehow detected or prevented against accidental unwanted adjustments. the idea occurred to me after seeing my phone attempt to block accidental screen touches, though i'm not sure how they do it.

possible idea for how it might be done in illustrator:

if object or path adjustment was made between very quick "mouse-click-on" and "mouse-click-off" events (less than 250ms is probably good), its highly likely, if not guaranteed, to be a mistake as nobody edits that quickly unless they are using a script (in which case there are no physical mouse clicks). An automatic "undo" command should be implemented in this scenario, and perhaps feedback in the form of a sound, or a visual cue with an icon next to the mouse cursor or something along those lines.
