It makes upgrades even more complicated. Remember a few things:

1) A regular [updates-]testing repository exposes only some users to
package releases which may or may not become official. This adds another
upgrade path. Do we work around bugs introduced in these updates? Do
enough active users enable such an optional repository, so that it would
become really helpful? I think Fedora Core Test Updates suffer from quite
some desinterest. Lack of feedback--also success reports--about test
updates doesn't help you to decide whether an update is good.

2) Will the build system build against the test updates or only against
official updates in the main repository? In case it builds against test
updates, what do we do if they are broken? And how are test updates pushed
or withdrawn when dependencies have or have not been built against them?
How does an additional repo solve the problem of insufficient
communication about upgrades and rebuilds of complete dependency chains?
