Wouldn't help if the user closes the drawer and moves it to the left - which users used to having apps to the left (and to a left to right reading culture) would.
The main problem I see is the mouse pointer has reason to be on the proximity of the left side: the Apple menu is there, the most important dock elements (on a bottom dock) are there - or the whole dock for a left-placed dock), the menubar File, Edit, etc, and the most common icons for icon bar operations are there.
And if 'content is king', navigating the content (TOC, search, thumbnail) should also be king, not just the current viewing page.
