These installs seem to be getting more complex. I'll stick with 0.3.21.

They are not any more complex than before, what do you think has made it "more complex"? Just install and be done with it. If worried about your wallet [which you should be], copy it aside, or in my case, I just take it as a good time to encrypt and back it up. I can always recover it and it is a process I do anyway.
