No, I move out of the way the config/data files I want to keep and move them 
back in after untarring the stage 3.

Quite, if you can get your existing installation to only run a minimal number 
of rebuilds to arrive at an upgraded toolchain, then the benefit of 
reinstalling wouldn't be there.  This could have been the case on an average 
year, when python deprecations didn't accelerate and EAPI didn't change.  If 
however you end up tying up yourself in knots with subsequent python upgrades 
and difficult to resolve conflicts, then the pain Vs gain calculus changes.
