Personally, there is nothing more I hate than a wild encounter. At best, there is nothing a shiny level 2 ratatta offers me. In the Gamefreak games I would probly' spend a good half hour using Cut on every square of grass just to avoid all unwanted battles. This was, of course, when I was too cheap and/or ran out of repels. Regardless, I would love to someday see this implemented in PRO as well, someday.
