I agree.  The devs did a good job with the safer method.  Some of us
just had some packages that were a little behind, for me, Kicad and a
couple other packages that likely not many people use compared to
something like Chrome, Firefox or LOo which was ready.  Still, the devs
can't help that some packages lag behind.  The important part, they gave
use a upgrade method that works even if it requires us to either delay
some packages or just delay the final step.  Once my odd packages caught
up, I was left with one package that still needs the old python.  Thing
is, my system remained stable during the whole thing. 

I have to say, emerge has come a LONG ways since 2003 when I started
using Gentoo.  Someone coming up with the idea of being able to inform
us of changes, with the news items, is also a HUGE help.  We get a
notice that something important is changing and might require certain
steps.  We not hitting these major changes blindly anymore.  I remember
the old days when I would sync and then emerge would puke all over my
keyboard with something most of us couldn't make sense of.  Today, we
sync, get a alert of serious changes that require attention and then
tells us how to navigate the change, usually with more than one way to
do it. 

Yea, Gentoo has come a long ways.  The devs do some awesome work.  Wish
I could win the lottery.  LOL  :-D

P. S.  I'm still trying to figure out how to redo my drive setup.  I got
one large LVM that I want to transfer to a encrypted file system.  I'm
trying to figure out how to put the new drives in or move the old drives
to the NAS box for the transfer.  Either way requires a lot of work.  :/
