Yes, but it's very much dependent on using a "frozen tree" mode as
we've discussed, because the emerge --dynamic-deps option is enabled
by default. The --dynamic-deps behavior causes the dependency graph
mutate when the portage trees or overlays mutate.

It doesn't exist because of the default --dynamic-deps behavior and
the lack of a "frozen tree" mode.
