How is this going to affect Google's indexing of the site? They hit the front page and follow links, right? They don't try random perturbations of the URLs and see if they resolve to something else? Or do they?
1) Users may (inevitably will) share links to the URLs on social media / wherever, and Googlebot et al will find those links and spider them.
2) The URLs will be sent to Google for any Chrome user with "Make searches & browsing better" setting enabled.
