Re: pre-building NEW packages, when they only introduce new binary packages
A missing build will only slow testing migration if the package wasn't
built when the unstable testing delay is over. Since almost all uploads
to NEW are low urgency, the build would need to take over 10 days to
affect the time to testing migration. To speed up testing migration due
to missing builds, it would be much more efficient to work on buildd
redundancy (or other improvements to the buildd network).
That probably won't make much time difference on "fast" archs (i386,
amd64 etc), but on slower ones like mips, mipsel etc (those sometimes
hold up testing transition :().
