Will start to reply but will take some time as I don't have much this
days :(

My idea is to add a comment about this because it's not obvious having
portage tree in a "common" partition with the rest of the system has
some problems like high fragmentation, waste of disk space and also
performance problems. I discovered it empirically when trying to get
"emerge -pvuDN world" a bit faster. 

Also, once a partition scheme is chosen when installing Gentoo at first
time, it's sometimes difficult to modify (for example, I was luck in my
cases because I had big swap partitions I shrinked a bit for portage
tree.

You can probably see it's "nice-to-have" (as partition scheme that is
shown in handbook showing partitions for /var, /home...), but it's
better than letting people put their portage trees in a standard
partition with the rest of the system
