Build-Depends should be set automaticaly as Dep-Wait for every source
upload. That would reduce a lot of needless work for both machines and
admins.

I think package urgency isn't considered because people would abuse it
to get their packages build faster, or so someone nameless fears.
Remember that the buildd queue is not FIFO at all. The queue has a
completly static order. Any changes to the queue are just packages
hiding because they are not "needs-build". I consider that the biggest
flaw of all in wanna-build.

Yes please. Packages should Dep-Wait automatically, should be ordered
by '(age * alpha) + beta' with alpha / beta set by at least the
package priority and upload urgency. Optionaly also the number of
Build-Depends and revers Build-Depends on the package.

If you can convince the w-b admins to allow changes I could send you
patches. Having a queue that will hapily starve packages is quite
unfair to maintainers. Next you know x* will be renamed to a* just to
get it build faster.
