Perhaps I am just contemplating a little deeper than you are.

Which happens to be the exact same method to get a stage3 upgraded also. 
Feel free to provide me with a link to better official documentation that
covers it.

I'm not talking about the past.  I can't travel through time and determine
what was and was not masked on your box.  The test condition was to get the
current stage3 installed with the current stable gcc, gcc-3.4.4 for x86.

In which case you would not be running a box with the current toolchain and
you would have to turn around and do it all over again later, therefore
wasting 4x the amount of time to get your stage3 and/or running install
upgraded.  To further educate you, there was a bug shortly after the
release of 3.4.4 into stable that did, in fact, automatically switch you
over to the new gcc.  It was in the toolchain eclass.

The test, what I am debating about, and my primary assertion is that the
stage3 installation method is not superior to the stage1/bootstrapping
installation method.  The official gcc migration instructions happen to be
the same for both a stage3 install and a running installation.  If you
cannot grasp nuanced discussion, I can't help you learn anything new.

No, they are not anywhere near the same.  The end goal is the same, how
effectively they get there and the predictability of reaching the desired
goal is very different.  If you find it a superior approach to go through
226 emerges instead of 99 over twice the amount of time to arrive at the
same destination, more power to you and the misinformed people who listen
to you.

Whatever.
