For instance: A bug in a package scriptlet, which touches some files and
damages them. Will the final update try to repair the damage?
Or: Accidentally dropped features, which are missing because a configure
script failed to detect upgraded build requirements and hence disabled
some pieces. In several applications, related configuration settings are
lost when features are removed (a concrete example is Sylpheed).
One thing for sure, both are scenarios which can happen. However, from a
user's perspective it must be clear in which ways another extras-testing
repository differs from the normal extras repository.
Increased risk -> possibly increased requirement to recover from broken
test updates -> the smell of guinea pigs -> the optional testing
repository does not become popular -> doubtful benefit.

Most likely because there is no convenient way to pull a package from the
needsign-repo [and any deps built against it]. And no way to put a lock on
a set of packages in the needsign queue in order to release the complete
set as a whole.
How about picking up the old idea of a "scratch target" instead?

As a counter-example, createrepo for FC4 and FC3 has still not been
updated to fix the broken deps in Extras' "plague". If the Test Update
repository were popular and helpful and if the developers believed in it,
the errata for FC4/FC3 would have happened already long ago.

? Is a package in extras/5, which is four weeks old, more safe to use
than a package in extras/5, which is two hours old? The age of a package
is irrelevant. The number of competent (!) testers who actually tested it
and report success or failure, is the interesting bit.

And *if* there is major breakage? Which pieces would you want to hold up?

Before that becomes possible we will need a way to mark packages which
depend on eachother, so they are only pushed together. Plus a way to
prioritise build jobs and releases (not just with security fixes in mind).

Automatically? So, Extras packagers must watch another moving target?

Then I must admit I don't understand the purpose of an extras-testing
repository (in the context of how we've been doing builds/releases for
quite some time).

Well, I see no users who scream and demand an extras-testing repository.
We must improve in the area of _Package Upgrade Guidelines/Policies_,
not create extra burden and artificial hurdles for the packagers.
