It wouldn't surprise me if the defaults on OS X are the same. #2 in particular, I consider that to be sensible autofocus behavior. If you don't want to replace the URL but instead modify it, just hit an arrow key. Partly this is because there are shortcuts to select the address bar to begin with, so I rarely use a mouse. It's generally consistent on mobile platforms too, to select the entire URL. You have to hold your finger a second time to position the cursor because the most common interaction with the URL bar usually means jumping somewhere entirely different. Edit: they could maintain a flag to change these behaviours though, if they were a concern. You could also build your own copy of the browser, patched as you wish... ;-)
