No, it's as grounded as it's going to get. Adding holes to the cap, dielectric grease on all ten connecting points, Dremeling off the corrosion, using your air compressor to blow everything out clean, and then wiping it down a bit with a clean rag that you've sprayed a little silicone lubricant on will reduce the corrosion's return significantly. You'll have to go back in and redo this chore every few years, but there's no performance impact unless you let the corrosion go hog wild.
