What breaks?

[Venusgate]

So I think I missed a release notes somewhere. Now that there are engineers that fix things, are there parts that break in stock? Or are engineers dependent on the Dangit! mod still?

Rover wheels and landing gears can break from a hard collision. Solar panels can break if you have them open in the atmosphere or if you bump into them. Engineer Kerbals can also repack parachutes.

I think that the utility of an engineer is pretty limited at the moment in stock. I think Mods can definitely make good use of Engineers though.
