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
