Yes it looks like the stench has been chipped. I remember the hold being smaller, harder to get the fingers into it. Now there is no 'lip' above the hold so it appears to be easier to get fat fingers into.
I haven't had a good look at it but will let you know what the story is next time I go over there.
And in regards to morialta's good rock and best routes they took the tools to muesli wall too... give me a call if you want the low down.
According to reports the retro chipper decided to enhance the hold due to the quality of climbers in 'deliade being so low. As there are so few good climbers round these parts we need a few more easier routes for the masses to top rope.
