You are correct.

Jarrod and I came to the conclusion that the sandbox packages will be moved out
of the sandbox. Packages that just need a home could go to scikits instead.
Packages intended for scipy itself can live under branches/ temporarily as a
standalone package until they are approved for inclusion. Maintainers who want
to build binaries of them can do so.
