It is already documented:

http://fedoraproject.org/wiki/ReleaseEngineering/SOP/BuildRootOverrides

although that page is buried in a somewhat obscure place that a casual
package maintainer would probably not know to look there.

It should probably linked from somewhere in the PackageMaintainers
namespace with a higher-level explanation like the text above.  This
kind of thing might be useful for the PackageMaintainers Tips/Tricks
page which I can't seem to locate the URL for right now (it isn't
linked from http://fedoraproject.org/wiki/PackageMaintainers)

As Todd said, you should request the buildroot override *before* you
push any packages to updates-testing so you can do them as a single
update.  That way prevents broken deps which should be discouraged
even in updates-testing.
